OK, this ebay auction has me ROFL: Decrease Your Erdos Number! If you’re a social networks geek, or a mathematician, physicist or computer scientist, you must check this out. Too funny. And there are even bids!
Update: Now that i’ve learned a bit more about the history and state of this auction, i thought i’d inform the curious reader of Jonah Peretti’s antics, normally called contagious media. Jonah set off a few memes of his own to see how they would spread – the Nike Sweatshop Email and the Rejection Hotline are my favorites.
