GiveSmart -- Shopping for a Good Cause

Just discovered a different kind of rewards program, thanks to the Museum of Modern Betas. The program is called GiveSmart and it's a lot like EmailCash or MyPoints, with one big difference -- the rewards you earn aren't for you, they go to various charitable causes -- fighting breast cancer, helping hurricane victims, etc.

From what I can tell, it involves using their toolbar for Internet Explorer, which pretty much counts me out, but if you're interested in shopping for a good cause, check 'em out.
