This past week's been full of interesting news and links.
Hello Health opened today in Williamsburg, Brooklyn. Maria from
Intueri and I were part of the crowd.

AppleQuack.com, a fantastic new productivity blog, presents the
top iPhone wallpapers for doctors.
It turns out I'm not the only blogging
nephrologist. Arnold Kim, the founder of
MacRumors.Com, recently decided to stop practicing medicine and devote all his time to blogging. He's interviewed in the New York Times: "
My Son, the Blogger: An M.D. Trades Medicine for Apple Rumors." (MacRumors, as an aside, has a Buyer's Guide which is a must-read if you're planning on buying a Mac.) More coverage at the
Wall Street Journal Health Blog.
Sandeep Jauhar writes about
the "night float" system — in which interns are required to care for patients during the night shift — in
Slate. (FWIW, my personal experience with night float was terrifying but invaluable.)
Wikipedia, which was never a particularly authoritative resource for medical information, now has plenty of competition. Google just released
Knol ("a unit of knowledge"), which allows anyone to author authoritative articles about any topic. Many of the topics on the home page, interestingly enough, are related to health and medicine.
Clinical Cases and Images has a review.
The Medpedia Project, in contrast, is a collaborative encyclopedia created by medical professionals. (You need to apply to write for Medpedia.)
A preview of the site is here.
And finally,
Nick Genes writes that he's passed on the stewardship of the medical blogosphere's Grand Rounds to
Dr. Val Jones and
Colin Son. Thanks for all your good work, Nick.
