Contagious Media Showdown

Philipp Lenssen writes "In the Contagious Media Showdown, competitors plant addictive memes to see who's best at viral marketing. The contest pages officially launched yesterday. The grand prize (most unique visitors) is $2000, with three other prizes at $1000 each for most links, most popular entry with a Creative Commons license, or first site with an Alexa ranking higher than 20,000."
