Web 2.0 Democracy

Social-media sites like Wikipedia and Digg are celebrated as shining examples of Web democracy, places built by millions of Web users who all act as writers, editors, and voters. In reality, a small number of people are running the show. According to researchers in Palo Alto, 1 percent of Wikipedia users are responsible for about half of the site's edits. The site also deploys bots—supervised by a special caste of devoted users—that help standardize format, prevent vandalism, and root out folks who flood the site with obscenities. This is not the wisdom of the crowd. This is the wisdom of the chaperones.

The same undemocratic underpinnings of Web 2.0 are on display at Digg.com. Digg is a social-bookmarking hub where people submit stories and rate others' submissions; the most popular links gravitate to the site's front page. The site's founders have never hidden that they use a "secret sauce"—a confidential algorithm that's tweaked regularly—to determine which submissions make it to the front page. Historically, this algorithm appears to have favored the site's most active participants. Last year, the top 100 Diggers submitted 44 percent of the site's top stories. In 2006, they were responsible for 56 percent.

At both Digg and Wikipedia, small groups of users have outsized authority. In the case of Wikipedia, this authority is both organic and institutionalized. A small segment of highly active users author the majority of the site's content; there are also elected site administrators who have the power to protect pages, block the IP addresses of problem users, and otherwise regulate Wikipedia's operations. At Digg, active users have more of a de facto authority over the site's goings-on (though there are persistent rumors that the site has "secret moderators" who delete content). But officially speaking, while the site's algorithm seems to favor devoted users, no individual Digger has the power to unilaterally delete a post.
