IdeaAid

Starting on Saturday, IdeaAid starts the world's first brainstorming benefit. Instead of sending your money, send your ideas to help solve the world's toughest problems. On Saturday, the first challenge is to find novel, easy ways of raising $1 billion annually to help eradicate global poverty.

IdeaAid is attempting to use the same social networking phenomenon that spreads the news of celebrity breakups to solve real social problems. If you've been wondering what all this linking, friending and tweeting is really good for, this is your chance to find out.

Find out how you can participate on the IdeaAid.com website.
