Plenty of Fish (POF) came in to change this, along with OKCupid (OKC) and a few others, offering the ability to do just about everything you needed to find someone, talk with them, and ultimately meet.
These are the free-ish dating sites, that have additional features to those willing to pay. Go 100% free, and deal with poor look and feel and less users (because of that), go to a free-ish site and use most of the features free, or pay for features on some of the bigger premium sites with the understanding that it's not cheap! I have had friends of friends who have met through Facebook and dated.
There is to date only one 100% free dating site that is focused on dating, and that is Date Hookup (DH), although it doesn't get the same traffic and looks and feels a bit weak and outdated. You would think Facebook would be an ideal spot for dating but in reality just seeing your friends friends is not enough people.
I don't really want to broadcast my dating habits to the world either.
But also you don't want to write a book either because you may not get a response.
I read a lot in the forums here and seems like the majority of guys don't get a hell of a lot of responses.
Facebook has since been the dominant social networking site, and even Google hasn't managed to step up to that level of interest.
