I've long been a reader of Andrew Sullivan. I've sometimes been critical (see here and here, for example), but have often thought he has worthwhile things to say. That's why it's so striking to see such empty political verbiage at his site, as in his recent attacks on Bush for ... being seen in the presence of beach volleyball players (more power to him) or making an odd expression. Attacks over nothing subtract credibility from whatever substantive posts Sullivan might still be writing. (Ann Althouse has some comments here.)
UPDATE: Some Bush/beach volleyball team video here.
