Keith Burgess-Jackson, whom I long ago dropped from my blogroll despite my very non-discriminatory linking policy*, has popped up again. Go see Leiter's post for a nice history of Keith's "weirdness" (to put it ever so mildly). Keith is a clear cut case of an academic whose blogging has devastated his career. I will refrain from further comment.
*I link to almost any blog run by M.A. students in philosophy on up. There are also one or two links in my sidebar to blogs run by advanced undergraduates, as well as a brief smattering of political blogs with a heavy philosophical bent.
