Tinder is so stupid.
Starting from the facebook login. Also people just don't talk. I guess they like being matched just for the fact of being liked by someone, the world is full of people needing validation and Tindr is great at that, also the fact that you can't send pictures... it's just a waste of time.
People just generally seem to use Grindr for hook-up purposes but Tinder seems more about 'relationships' rather than just finding a **** buddy, so naturally I'd go for Tinder.
