Orac is the first, in the annals of blogdom, to complete this hat trick: He's hosted the Skeptics' Circle, Grand Rounds, and now, Tangled Bank.

Offer him your congrats. And hey, somebody start up a new weekly science roundup for him to host! (my suggestion: Carnival of the Colonoscopists).

Orac's theme (as usual) is original -- he's fashioned the Tangled Bank roundup of science posts as a letter to a journal editor from a disgruntled manuscript author. Check it out.

UPDATE Ann's Fuse Box has spearheaded the challenge and is going to maintain a frequently-updated Carnival of the Carnivals. At last! The power of Grand Rounds -- with its collected writings of doctors, nurses, and health professionals -- is now presented alongside pictures of cats.
