Nice to see ben goldacre's writings up on here. He is a clinical epistemologist by training but he has rapidly moved into the world of science journalism (or perhaps meta-journalism) due to his popularity as a writer and speaker.
He also has a secondary blog where he posts "things that are too long to post on twitter and not clever enough to post on his main blog": http://bengoldacre.posterous.com/
Yeah, Ben Goldacre is a great read. If you are interested in bad science from a medical angle (as opposed to 'creationists are being silly' kind), then check out his book Bad Science or the rest of his website
