Creationists are in the habit of finding "scientists who doubt evolution" or "scientists who dissent from Darwinism." When they find these strange people they put their names on long lists as testaments to the idiocy of Evolution. Project Steve is an Evolutionary reaction. They've only asked scientists named Steve and Stephanie to add their name to their list (already it beats the pants off the Creationist list for saddos willing to put their name on a petition).
This story is nowhere near as entertaining as the Steve Song though, it's the anthem of the Steve List. Have a listen, you'll be singing the chorus all day.
ps. Creationism prefers to be called Creation Science. Now that's even funnier than the song.
