Ya like evolution? Named Steve (Stephen, Stephanie, or the like)? Sign up with Project Steve! The idea is simple - Creationists like to circulate lists of names of scientists that doubt evolution, and Project Steve seeks to mock these lists by listing the scientists that agree with evolution. The catch is, of course, you have to have the name Steve.
On a more serious note, there's SEFORA - Scientists and Engineers for America. Wanna see more emphasis on good science in politics? Check them out.
