Thoughtpile

Sharing ideas. Not exactly a new idea, but I kind of like the interface on this. In their own words:

"Thoughtpile is an open invitation to share your best ideas with the world."

Basically, they come up with a topic, and you come up with answers. Then people can vote on them. You know, like Yahoo! Answers...but a lot prettier. Plus you get to win stuff if your answer gets the most votes at the end of the week (specifically a Herman Miller Embody chair. yes, this is a ploy to sell stuff).

So go ahead, jump into the Thoughtpile.
