"It's April 21st, and everybody knows today is Earth Day, Merry Christmas, Happy Birthday to whoever's being born."

In celebration of Earth Day (and obscure Dramarama references), here's something a little different: I've taken on hosting responsibilities for The Tangled Bank, a bi-weekly showcase of the best science weblog entries. If you publish a science blog and would like to submit one of your posts, head to the website and check it out. You can also check out the first edition at Pharyngula.
