Interesting part of this article is ofcourse the churnrate or disloyalty of dating focussed social networks. Gives me the idea that dating is more of an add-on application for your social network. Something you can switch on and off.
Seems every day now you hear about another social network startup. From what people in the industry have been telling me there are between 300 and 400 new social networking/dating startups in the last 2 years. Only 4 or 5 of those sites will be around in another 4 or 5 years.
