Chris Bowers, a liberal blogger, [myDD] has done a bit of interesting analysis on why liberal blogs have significantly overtaken conservative blogs based on blogads statistics. Read it here.
His thesis, basically, is that many liberal blogs are community oriented, are more inclusive, are much more heterogeneous and therefore interesting. Conservative blogs, he posits, tend to be standalone and aloof with most not even allowing comments.
Jonathan Last has thoughts here and some of the comments make valid counterpoints. Specifically the impact of conservative blogs has been quite significant whereas liberal blogs have had little or no impact and are largely angry 'circlejerks' with rants that appeal only to like-mineded readers.
