Here's how it works: 1a. if you are posting a "roommate wanted" ad on, say craigslist (CL), you log into tpot using Facebook, create a trust link, and paste it in your description on CL. 1b. If you are responding to a CL ad, again log into tpot, create a trust link, and send it with your response. 2. When the other party clicks on it, they (and you) see the following info: - If you and them are within 3 hops (friend of a friend of a friend) of each other on FB. - Which of your friends are you connected to them through. - If you went to the same school, grew up in the same town, and/or worked for the same employer.

This info will help you (and them) make a more informed decision about renting/roommates.

This also works in other settings which require a high degree of trust: ride shares, finding cofounders, contract jobs, etc.
