Dr Hall had a gig writing for Oprah's woo-laden magazine, and I didn't even know it (that tells you how often I've looked at O), and it was a good plan: she'd be writing a skeptical column for them that would address common medical myths. Unfortunately, reality smacked hard into the jello of pop pseudo-medicine, passed through quickly, and Dr Hall now finds herself not writing for Oprah. She didn't belong in that den of inanity anyway.
One amusing thing, though: compare the comments discussing her departure at Science-Based Medicine with those on Gawker. Right out of the gate, the Gawker commenters are whining that science doesn't know everything, and wondering what's wrong with Reiki, and accusing Dr Hall of all kinds of egotistical perfidy.
