In contradiction to my post below, apparently at least Martini Republic agrees with the "Osama knew that this would be used to help Bush" theory.
Edit: Never mind. It looks like I wasn't the only one rousted into posting by Osama. Billmon is back.
By the way, I hadn't really weighed in on Billmon's attack on the professionalization of blogging. (Not linked- AFAIK it isn't available in a public archive). I had mentioned that the massive concentration on a few key sites was a problem, but I don't buy that it's ruining blogging, just that it has lead to somewhat of a "rich get richer, poor get poorer" distribution of eyeballs on the left. Atrios and Kos have their huge audiences largely because they're excellent commentators and update constantly. Many other worthy bloggers don't fit either the former or latter criterion (largely the latter), and that's natural enough as well. A professional needs to be both, but blogger isn't going anywhere, and as long as it's around so will the larger community.
