We'll now open this up to Q&A

There's lots of good stuff from the medical blogosphere at this week's Grand Rounds, hosted by the Hospice Guy.

For example, Orac over at Respectful Insolence has a great post about people who you always see come up to the microphone for the Q&A portion of a session. While he's mainly talking about medical/surgical conferences, I've seen these types at just about every meeting I've ever been to--I bet you have, too. Check it out, it's pretty funny.
