Tinder is considered a success? I've used it and maybe I'm just a loser, but my experience and I believe the general consensus is that it is mostly for hookups. I am highly doubtful that women are meeting men that are actually interested in a long term relationship. There are a lot of issues with Tinder that have already been mentioned in this thread, such as 20% of the guys (I'm betting on less) get most of the likes and that women are the gatekeepers; which is good for them not having to trudge through spam, but it perpetuates the problem that guys already have IRL at social scenes and just keeps the women playing into the players' hands.
