When the fourth annual Netroots Nation conference opens today at the David L. Lawrence Convention Center, there will be plenty of familiar names from the liberal blogosphere, from President Bill Clinton to Howard Dean to Ron Reagan Jr. to "Kos," a.k.a. Markos Moulitsas Zuniga, founder of Daily Kos, the largest community blog in the country.

But there will be many more members of the netroots you may have never heard of. TexDem, Kitsap River, Mindoca, for starters -- all fellow "Kossacks" who blog on Daily Kos but use it as much more than just a platform to vent about politics. Netroots, a blending of Internet activism and grass-roots supporters, is a term coined during Mr. Dean's 2004 presidential campaign.

Mr. Clinton, Mr. Dean and Valerie Jarrett, a top adviser to President Barack Obama, will be keynote speakers at the convention, which will feature sessions on everything from "fearless campaigning" and "global solutions for global poverty" to "taking health reform online" and "writing an effective blog post."
