Interesting study out of the Berkman center at Harvard here.
Notably, we find evidence of an association between ideological affiliation and the technologies, institutions, and practices of participation across political blogs. Sites on the left adopt more participatory technical platforms; are comprised of significantly fewer sole-authored sites; include user blogs; maintain more fluid boundaries between secondary and primary content; include longer narrative and discussion posts; and (among the top half of the blogs in our sample) more often use blogs as platforms for mobilization as well as discursive production.

This seems to tie in quite closely to the ongoing discussion I am in over at the Social Epistemology Review and Reply Collective. The link is to a critical discussion of my article ‘The New Political Blogosphere’ in Social Epistemology 26(1), 55-70.
