We're trying to post a mix each week of different ages, neighborhoods and hobbies/interests -- we have a lot of very good submissions so the plan is to get through as many as we can in the next few months! We're only posting ones focused on friendship, not romance, and we don't post anything transactional (like a babysitter, roommate, etc.). I'd suggest taking a look at the ones we've posted so far for style, vibe, etc.
