Here's Kos himself:
Don't look now, but Republicans are crushing Democrats in the use of social networks.
R's have an avg. of 38,718 FB friends and 14,009 Twitter followers.
D's have an avg. of 8,260 FB friends and 2,591 Twitter followers according to HeadCount.org
This stuff matters. Republican consultants have embraced the social networks as a way to spread their message in a way that our shitty Democratic ones have not. What online advantages progressives have -- the blogosphere and sites like ActBlue -- have been created outside of the establishment's grasp. Otherwise, we'd be even more fucked.
