This is going to be a really quick diary.
PZ Myers, proprietor of the Pharyngula blog, defender of science and outspoken atheist, is undergoing major heart surgery.
He first announced his health issues just a couple of days ago, and reported late last night that the condition is very serious. He's having a bypass operation today (in his words, today is "the scary day".)
So, drop by his blog and send along a message of support (or some pictures of cephalopods). He's got the best of modern medicine and lots of people who care about him on his side, so here's hoping everything goes swimmingly.
UPDATE 8/25, 8AM:
Good news: PZ is out of surgery; the docs determined he didn't need a bypass after all and was instead fitted with a set of stents. He's recovering and doing OK.
