The Digital Divide

  For example, at the first Web 2.0 conference, in October 2004, John Battelle and I listed a preliminary set of principles in our opening talk. The first of those principles was “The Web as platform.” Yet that was also a rallying cry of Web 1.0 darling Netscape, which went down in flames after a heated battle with Microsoft. What’s more, two of our initial Web 1.0 exemplars, DoubleClick and Akamai, were both pioneers in treating the Web as a platform. People don’t often think of it as “Web services,” but in fact, ad serving was the first widely deployed Web service, and the first widely deployed “mashup” (to use another term that has gained currency of late). Every banner ad is served as a seamless cooperation between two websites, delivering an integrated page to a reader on yet another computer. Akamai also treats the network as the platform, and at a deeper level of the stack, building a transparent caching and content delivery network that eases bandwidth congestion.

  Nonetheless, these pioneers provided useful contrasts because later entrants have taken their solution to the same problem even further, understanding something deeper about the nature of the new platform. Both DoubleClick and Akamai were Web 2.0 pioneers, yet we can also see how it’s possible to realize more of the possibilities by embracing additional Web 2.0 design patterns.

  FACING PAGE: Figure 1 shows a “meme map” of Web 2.0 that was developed at a brainstorming session during Foo Camp, a conference at O’Reilly Media. It’s very much a work in progress, but shows the many ideas that radiate out from the Web 2.0 core.

  WEB 2.0 MEME MAP

  Let’s drill down for a moment into each of these three cases, teasing out some of the essential elements of difference.

  Netscape vs. Google

  If Netscape was the standard-bearer for Web 1.0, Google is most certainly the standard-bearer for Web 2.0, if only because their respective IPOs were defining events for each era. So let’s start with a comparison of these two companies and their positioning.

  Netscape framed “the Web as platform” in terms of the old software paradigm: their flagship product was the Web browser, a desktop application, and their strategy was to use their dominance in the browser market to establish a market for high-priced server products. Control over standards for displaying content and applications in the browser would, in theory, give Netscape the kind of market power enjoyed by Microsoft in the PC market. Much like the “horseless carriage” framed the automobile as an extension of the familiar, Netscape promoted a “webtop” to replace the desktop, and planned to populate that webtop with information updates and applets pushed to the webtop by information providers who would purchase Netscape servers.

  In the end, both Web browsers and Web servers turned out to be commodities, and value moved “up the stack” to services delivered over the Web platform.

  Google, by contrast, began its life as a native Web application, never sold or packaged, but delivered as a service, with customers paying, directly or indirectly, for the use of that service. None of the trappings of the old software industry are present. No scheduled software releases, just continuous improvement. No licensing or sale, just usage. No porting to different platforms so that customers can run the software on their own equipment, just a massively scalable collection of commodity PCs running open-source operating systems plus homegrown applications and utilities that no one outside the company ever gets to see.

  At bottom, Google requires a competency that Netscape never needed: database management. Google isn’t just a collection of software tools; it’s a specialized database. Without the data, the tools are useless; without the software, the data is unmanageable. Software licensing and control over APIs—the lever of power in the previous era—is irrelevant because the software never need be distributed but only performed, and also because without the ability to collect and manage the data, the software is of little use. In fact, the value of the software is proportional to the scale and dynamism of the data it helps to manage.

  Google’s service is not a server—though it is delivered by a massive collection of Internet servers—nor a browser—though it is experienced by the user within the browser. Nor does its flagship search service even host the content that it enables users to find. Much like a phone call, which happens not just on the phones at either end of the call, but on the network in between, Google happens in the space between browser and search engine and destination content server, as an enabler or middleman between the user and his or her online experience.

  While both Netscape and Google could be described as software companies, it’s clear that Netscape belonged to the same software world as Lotus, Microsoft, Oracle, SAP, and other companies that got their start in the 1980s software revolution, while Google’s fellows are other Internet applications like eBay, Amazon, Napster, and, yes, DoubleClick and Akamai.

  DoubleClick vs. Overture and AdSense

  Like Google, DoubleClick is a true child of the Internet era. It harnesses software as a service, has a core competency in data management, and, as noted above, was a pioneer in Web services long before Web services even had a name. However, DoubleClick was ultimately limited by its business model. It bought into the ’90s notion that the Web was about publishing, not participation; that advertisers, not consumers, ought to call the shots; that size mattered; and that the Internet was increasingly being dominated by the top websites as measured by MediaMetrix and other Web ad scoring companies.

  As a result, DoubleClick proudly cites on its website “over 2,000 successful implementations” of its software. Yahoo! Search Marketing (formerly Overture) and Google AdSense, by contrast, already serve hundreds of thousands of advertisers apiece.

  Overture and Google’s success came from an understanding of what Chris Anderson refers to as “the long tail,” the collective power of the small sites that make up the bulk of the Web’s content. DoubleClick’s offerings require a formal sales contract, limiting their market to the few thousand largest websites. Overture and Google figured out how to enable ad placement on virtually any Web page. What’s more, they eschewed publisher/ad-agency-friendly advertising formats such as banner ads and pop-ups in favor of minimally intrusive, context-sensitive, consumer-friendly text advertising.

  The Web 2.0 lesson: leverage customer-self service and algorithmic data management to reach out to the entire Web, to the edges and not just the center, to the long tail and not just the head.

  Not surprisingly, other Web 2.0 success stories demonstrate this same behavior. eBay enables occasional transactions of only a few dollars between single individuals, acting as an automated intermediary. Napster (though shut down for legal reasons) built its network not by building a centralized song database, but by architecting a system in such a way that every downloader also became a server, and thus grew the network.

  Akamai vs. BitTorrent

  Like DoubleClick, Akamai is optimized to do business with the head, not the tail, with the center, not the edges. While it serves the benefit of the individuals at the edge of the Web by smoothing their access to the high-demand sites at the center, it collects its revenue from those central sites.

  BitTorrent, like other pioneers in the P2P movement, takes a radical approach to Internet decentralization. Every client is also a server; files are broken up into fragments that can be served from multiple locations, transparently harnessing the network of downloaders to provide both bandwidth and data to other users. The more popular the file, in fact, the faster it can be served, as there are more users providing bandwidth and fragments of the complete file.

  BitTorrent thus demonstrates a key Web 2.0 principle: the service automatically gets better the more people use it. While Akamai must add servers to improve service, every BitTorrent consumer brings his own resources to the party. There’s an implicit “architecture of participation,” a built-in ethic of cooperation, in which the service acts primarily as an intelligent broker, connecting the edges to each other and harnessing the power of the users themselves.

  The central principle behind the success of the giants born in the Web 1.0 era who have survived to lead the Web 2.0 era appears to be that they have embraced the power of the Web to harness collective intelligence:• Hyperlinking is the foundation of the Web. As users add new content, and new sites, it is bound in to the structure of the Web by other users discovering the content and linking to it. Much as synapses form in the brain, with associations becoming stronger through repetition or intensity, the web of connections grows organically as an output of the collective activity of all Web users.

  • Yahoo!, the first great Internet success story, was born as a catalog, or directory of links, an aggregation of the best work of thousands, then millions of Web users. While Yahoo! has since moved into the business of creating many types of content, its role as a portal to the collective work of the Net’s users remains the core of its value.

  • Google’s breakthrough in search, which quickly made it the undisputed search market leader, was PageRank, a method of using the link structure of the Web rather than just the characteristics of documents to provide better search results.

  • eBay’s product is the collective activity of all its users; like the Web itself, eBay grows organically in response to user activity, and the company’s role is as an enabler of a context in which that user activity can happen. What’s more, eBay’s competitive advantage comes almost entirely from the critical mass of buyers and sellers, which makes any new entrant offering similar services significantly less attractive.

  • Amazon sells the same products as competitors such as Barnesandnoble.com, and they receive the same product descriptions, cover images, and editorial content from their vendors. But Amazon has made a science of user engagement. They have an order of magnitude more user reviews, invitations to participate in varied ways on virtually every page—and even more important, they use user activity to produce better search results. While a Barnesandnoble.com search is likely to lead with the company’s own products, or sponsored results, Amazon always leads with “most popular,” a real-time computation based not only on sales but other factors that Amazon insiders call the “flow” around products. With an order of magnitude more user participation, it’s no surprise that Amazon’s sales also outpace competitors’.

  Now, innovative companies that pick up on this insight and perhaps extend it even further are making their mark on the Web:• Wikipedia, an online encyclopedia based on the unlikely notion that an entry can be added by any Web user, and edited by any other, is a radical experiment in trust, applying Eric Raymond’s dictum (originally coined in the context of open source software) that “with enough eyeballs, all bugs are shallow” to content creation. Wikipedia is already in the top 100 websites, and many think it will be in the top ten before long. This is a profound change in the dynamics of content creation!

  • Sites like del.icio.us and Flickr, two companies that have received a great deal of attention of late, have pioneered a concept that some people call “folksonomy” (in contrast to taxonomy), a style of collaborative categorization of sites using freely chosen keywords, often referred to as tags. Tagging allows for the kind of multiple, overlapping associations that the brain itself uses, rather than rigid categories. In the canonical example, a Flickr photo of a puppy might be tagged both “puppy” and “cute”—allowing for retrieval along natural axes-generated user activity.

  • Collaborative spam-filtering products like Cloudmark aggregate the individual decisions of e-mail users about what is and is not spam, outperforming systems that rely on analysis of the messages themselves.

  • It is a truism that the greatest Internet success stories don’t advertise their products. Their adoption is driven by “viral marketing”—that is, recommendations propagating directly from one user to another. You can almost make the case that if a site or product relies on advertising to get the word out, it isn’t Web 2.0.

  • Even much of the infrastructure of the Web—including the Linux, Apache, MySQL, and Perl, PHP, or Python code involved in most Web servers—relies on the peer-production methods of open source, in themselves an instance of collective, Net-enabled intelligence. There are more than 100,000 open source software projects listed on SourceForge.net. Anyone can add a project, anyone can download and use the code, and new projects migrate from the edges to the center as a result of users putting them to work, an organic software adoption process relying almost entirely on viral marketing.

  The lesson: Network effects from user contributions are the key to market dominance in the Web 2.0 era.

  Blogging and the Wisdom of Crowds

  One of the most highly touted features of the Web 2.0 era is the rise of blogging. Personal home pages have been around since the early days of the Web, and the personal diary and daily opinion column around much longer than that, so just what is the fuss all about?

  At its most basic, a blog is just a personal home page in diary format. But as Rich Skrenta notes, the chronological organization of a blog “seems like a trivial difference, but it drives an entirely different delivery, advertising and value chain.”

  One of the things that has made a difference is a technology called RSS. RSS is the most significant advance in the fundamental architecture of the Web since early hackers realized that CGI could be used to create database-backed websites. RSS allows someone to link not just to a page, but to subscribe to it, with notification every time that page changes. Skrenta calls this “the incremental Web.” Others call it the “live Web.”

  Now, of course, “dynamic websites” (i.e., database-backed sites with dynamically generated content) replaced static Web pages well over ten years ago. What’s dynamic about the live Web are not just the pages, but the links. A link to a weblog is expected to point to a perennially changing page, with “permalinks” for any individual entry, and notification for each change. An RSS feed is thus a much stronger link than, say, a bookmark or a link to a single page.

  RSS also means that the Web browser is not the only means of viewing a Web page. While some RSS aggregators, such as Bloglines, are Web-based, others are desktop clients, and still others allow users of portable devices to subscribe to constantly updated content.

  RSS is now being used to push not just notices of new blog entries, but also all kinds of data updates, including stock quotes, weather data, and photo availability. This use is actually a return to one of its roots: RSS was born in 1997 out of the confluence of Dave Winer’s “Really Simple Syndication” technology, used to push out blog updates, and Netscape’s “Rich Site Summary,” which allowed users to create custom Netscape home pages with regularly updated data flows. Netscape lost interest, and the technology was carried forward by blogging pioneer Userland, Winer’s company. In the current crop of applications, we see, though, the heritage of both parents.

  But RSS is only part of what makes a weblog different from an ordinary Web page. Tom Coates remarks on the significance of the permalink:It may seem like a trivial piece of functionality now, but it was effectively the device that turned weblogs from an ease-of-publishing phenomenon into a conversational mess of overlapping communities. For the first time it became relatively easy to gesture directly at a highly specific post on someone else’s site and talk about it. Discussion emerged. Chat emerged. And—as a result—friendships emerged or became more entrenched. The permalink was the first—and most successful—attempt to build bridges between weblogs.

  In many ways, the combination of RSS and permalinks adds many of the features of NNTP, the Network News Protocol of the Usenet, onto HTTP, the Web protocol. The “blogosphere” can be thought of as a new, peer-to-peer equivalent to Usenet and bulletin boards, the conversational watering holes of the early Internet. Not only can people subscribe to each other’s sites, and easily link to individual comments on a page, but also, via a mechanism known as trackbacks, they can see when anyone else links to their pages, and can respond, either with reciprocal links or
by adding comments.

  Interestingly, two-way links were the goal of early hypertext systems like Xanadu. Hypertext purists have celebrated trackbacks as a step towards two-way links. But note that trackbacks are not properly two-way—rather, they are really (potentially) symmetrical one-way links that create the effect of two-way links. The difference may seem subtle, but in practice it is enormous. Social networking systems like Friendster, Orkut, and LinkedIn, which require acknowledgment by the recipient in order to establish a connection, lack the same scalability as the Web. As noted by Caterina Fake, cofounder of the Flickr photo-sharing service, attention is only coincidentally reciprocal. (Flickr thus allows users to set watch lists—any user can subscribe to any other user’s photostream via RSS. The object of attention is notified, but does not have to approve the connection.)

  If an essential part of Web 2.0 is harnessing collective intelligence, turning the Web into a kind of global brain, the blogosphere is the equivalent of constant mental chatter in the forebrain, the voice we hear in all of our heads. It may not reflect the deep structure of the brain, which is often unconscious, but is instead the equivalent of conscious thought. And as a reflection of conscious thought and attention, the blogosphere has begun to have a powerful effect.

  First, because search engines use link structure to help predict useful pages, bloggers, as the most prolific and timely linkers, have a disproportionate role in shaping search engine results. Second, because the blogging community is so highly self-referential, bloggers paying attention to other bloggers magnify their visibility and power. The “echo chamber” that critics decry is also an amplifier.
