Perhaps it's an age thing, but for the younger crowd (post college, mostly, say 22-26 or so) this is a fairly useful service, as you're done with college, and presumably working (or at home), and your dating pool has dropped off considerably, along with your constant opportunities to meet people. This is an added connection to compensate for that.
suppose the younger crowd is more familiar and accepting with using online resources like this as well, which helps. I also screened out anyone with kids or without pictures. I was just looking for someone similar to me, who had since broken up with the college ex, and was looking to start over. Wasn't looking to be a substitute father, or to "rescue" some girl from failed relationships or background. Just using it as another way to meet people other than at a bar...
I've never understood "meeting people" at a bar.
I meet people at the bar all the time.
More precisely, I meet their feet at the end of the night.
