Bill Keller.
You know, even if we granted Keller his assertion that "Bloggers recycle and chew on the news," that pretty much describes 65% of what cable news networks do (and about 80% of what they do in prime time), 95% of what columnists do (including BK himself not so long ago), and 99% of what talk radio hosts do.
I welcome a long hard look at what the news media has become, but it starts with having an awareness of what the institutional media has become, and not with taking broad brush potshots at bloggers.
