This is just untrue. Plenty of Fish launched in 2003. Okcupid in 2004. Both clearly listed on wikipedia. What is going on with modern journalism? I'm supposed to put faith in the rest of the article, when the author can't get basic facts straight?
What I'd really like to see is a piece on how dehumanizing the online dating game is for men. Yeah, women complain about being sex objects, but all men online are treated with a heavy suspicion of wanting only sex.
I think there's a greater developing problem in Western society with hypergamy, but no one is paying any attention to the bottom 20-30% of men who are involuntarily single, and it's only going to get worse, as the idea of male privilege breaks further into the mainstream while ignoring the relative difficulty that modern men increasingly have with romantic fulfilment.
Romantic companionship is part of Maslow's Heirarchy for a reason. Having a substantial proportion of the populous lonely and depressed because of unfulfillment of a basic need can't be good for society.
And this isn't as easy as simply working on oneself when hypergamy is shifting female standards further and further out of reach of the average male.
Perhaps it is time for women to start checking their own privilege.
