Good idea. I build SMB products, so I have an older target demographic. I've found jury duty a great place to get feedback as well due to the ages and type of people that end up there.<p>It works well because it's scheduled and after going a couple times you know how long you have until any given person or group has to leave. Just get to the waiting room early, sit in the back, then start striking up conversations as people who fit your demographic file in.<p>I've found people are more willing to chat at jury duty than the DMV. At the DMV they typically have some (misguided) hope of getting out of there quickly. At jury duty there is no hope. There's just a sort of quiet resignation that they'll be there all day (or maybe even all week).
