I discovered that there are many fake profiles on Tinder so I use it for entertainment only. After using it a while you will get a lot of matches but many of them go nowhere. It can be a numbers game sometimes.
Functionality is good and I can tell why Tinder become so popular. It is a little addictive. Like I wrote in the beginning it is perfect for entertainment. If you are serious about meeting someone, I'd still go for the traditional online dating sites. There are plenty of good options like Mingle2day, Cupid, Match and OKC.
