The X PRIZE Foundation finally has a group on facebook, joining all of our active prizes. Not sure why it took so long, but better late than never, right?
Here's the link: http://www.facebook.com/pages/X-PRIZE-Foundation/35962698116
At the time of writing, we're at about 12 fans (it's only been up for an hour). We're looking for a lot more, so please join up!
