We've met some really great people and made some good connections. It may vary greatly depending on the region you are in. The interesting conversation are mainly after the pickup lines. Sometimes people would ask about polyamory, sometimes it'd just be a conversation that'd strike up when we were getting to know each other.
We had a pretty ideal experience with a wonderful woman. It was really ideal except that her long-distance boyfriend insisted it be a one time thing for her. It would have been so great to get a lasting thing going with her, she was super hot, we all hit it off great, and she lives like two blocks away. We keep trying but haven't gotten anyone to respond for a while now. We're also in Manhattan which helps the numbers. We've had dozens of matches; I swipe up iniscriminatley and only get lucky after matching.
