One of the blogosphere's best known skeptics hit a milestone today. Orac at Respectful Insolence has now been fighting ignorance for five years. That's like, oh, about 30 in blog years. Why don't you go over there and wish him a happy blogiversary. He deserves it. Folks like Orac who publicly call out quacks get a lot of online and real-life harassment. It's nice to get well-wishers coming by once in a while.
