WHO IS THE BLOGOSPHERE? Chris Bowers's analysis of the demographics of the progressive blogosphere is well worth a read. In sum, "Active readers of Democratic political blogs are very highly educated, highly politically active, quite well-to-do, voracious consumers of media, not very young, and skew male." Bowers thinks this runs contrary to stereotype, but to me the only surprising thing about this was the median age (46.4 years) which was quite a bit higher than I would have expected. This is, interestingly, more or less the demographic profile of professional journalists, which perhaps accounts for the mutual antagonism (narcissism of small differences and all that).
