While on the train back from my girlfriend's house, I whiled away the hours making ThinkLink, a site that uses various association techniques to find others while think like you. After signing up, you just type the first thing that pops into your head when you read the idea, or look at the picture. After doing 20+ of these, you can click on your name to see other's who made the same associations as you did, I just did it to keep myself busy, but it's very interesting to see how closely some of my best friends are linked together, even though they have not met. It's still very much in its infancy, but feel free to give it a shot.
Peace and chow,
