Netroots Nation, formerly YearlyKos Convention started by dailykos.com founder Markos Moulitsas Zuniga, kicks off today in Austin, Texas.  According to Katherine Q. Seelye of the New York Times, “The convention, formerly YearlyKos and now Netroots Nation, or NN08, bills itself as “the most concentrated gathering of progressive bloggers to date.” About 2,000 bloggers, activists, office-holders, vendors and others are expected to attend, with 200 members of the mainstream media tracking them (yes, roughly one old-media type for every 10 new-media hipsters.).”

Here’s the full agenda that includes several panels from representatives of Barack Obama’s campaign.
