So some of you may have already heard of this place, but I just found it and think it's cool. You've heard all that hubub about micro lending? Well, you can get in on it if you want.
Kiva.org lets you lend as little as $25 (and at the moment only $25 since it's so popular) to specific third world entrepreneurs. They each have little blurbs about what the want the money for and when they will pay it back. I don't really have the money right now, but I'm honestly tempted... I mean, it's only $25, and the risks seem minimal for a lot of these people, though you wouldn't be earning any interest on the money.
