Topix is online news community that aims to connect people to the information and discussions that matter to them in every U.S. town and city. Chris Tolles, founder and CEO of the company, talks about the evolution of the rapidly growing site and the kinds of news and commentary that are popular on Topix. Chris also addresses the number of page views and demographics of Topix contributors and readers. Finally, Chris elaborates on the Google Adsense driven business model, advertisers' growing comfort level with user generated content, time to profitability of the site, and how Topix measures popularity of stories on a local level (whereas sites like Diggit or Reddit provide popularity measures on a national level).
