This is a clever: the Periodic Table of Science Bloggers!
David Bradley at Sciencebase took the periodic table of elements and associated each element symbol with a science blog. I've read quite a few of them, and they're pretty good -- though I wonder about using Jack of Kent; it's a great blog (he has been terrific about explaining the Simon Singh libel case), but it's about legal issues, not science ones! Still, lots of good blogs there. Of course, being the egomaniacal monster that I am, my first thought was, "Hey, I wonder what he used for barium?", since my encyclopedic knowledge of the elements informs me that barium's symbol is, haha, Ba. And guess what? Hey, wait a sec! I got robbed.
