I'm enjoying the Changemakrs website:

The barebones site quickly went viral, accumulating 3 million pageviews in about 48 hours. Surprised by the response to such a simple concept, they redid it with other figures. They did it with Yoda, and got 300,000 visitors. Then they did it again with Albert Einstein, and immediately got 400,000 visitors. Again, they did it with Lady Gaga, and got 700,000 visitors with 16 percent of them clicking through to a music track.

Insanity: doing the same thing over and over again and expecting different results. ~Albert Einstein
