Mark Glaser interviews Patrick Ruffini; Rolling Stone glowingly investigates Obama's grassroots game; Mike Connery at TPMCafe; who's winning the Wikipedia primary?; Flickr for Good launches; and the candidates do some, er, interesting things with splash pages.

Rounding up last night's results, explanations, and prognostications; what's CNN? Online politicos tracked the action with Twitter, Google Maps, Flickr, and YouTube instead; Hillary is favored by Microsoft employees, Barack by Google: Hillsoft vs. Goobama?; Voices without Votes gives us international impressions of the race; what do we see when we take a closer look at John McCain?; and online advertising is stuck in the dark ages.

Welcome to our new group blog on how the presidential campaigns are using the web, and how the web is using them, TechPresident.com. This blog is an extension of Personal Democracy Forum, our online zine and annual conference on how technology is changing politics. Over there, we'll continue to cover all the ways the political arena is being reshaped by new tools and practices born on the web, while over here we're going to drill down on what the presidential campaigns are doing online, and vice-versa, how bottom-up initiatives launched by ordinary people, what we call voter-generated content, are going to impact the campaign.
