Found this whilst poking around our SiteMeter readings. It's healthcare100.com's World's Top Blogs on Health and Medicine:
We're in the top third (#31, to be exact), near our friends the Health Care Economist and the Health Affairs blog. Nice company, to be sure. I really don't know much about this site, but it's always nice to be in the upper levels of any "Top 100" list.
[ed: I'm sure that Bob will have one or two examples to disabuse you of that notion]
