NY Mag helps to feed the flames.

“Last fall, the How’s My Dealing? blog (which rates gallerists’ treatment of their artists according to anonymous informants) began a gallery “DeathWatch” thread—and dealers are on edge over its retailing of unsubstantiated rumors.”

I checked out the site and it’s pretty interesting. My only criticism is it’s really hard to read and navigate. You can decide for yourself. Check out the NYmag article and check out How’s my Dealing.
