yeah, but giving rides from SFO is time consuming and costly. Gas could easily cost you $10, not to mention an hour of time. There's easier ways to do it, and as a startup, you need to be as resourceful as possible.
We'll give union square a try as well, but this free ride & test idea seems to work well so far. A good test of the app takes 45-60 minutes, which works well for an average ride of 30-45 mins. The time wasted on finding candidates is minimal - few postings and replying to email.
