I've been on a few dating sites in the past. Nothing positive on the dating, or romance, front became of it. I was on Plenty of Fish for a few years—I'd have to say the most positive thing about my experience there was interacting with other members on the forums and learning all the bad crap about the online dating culture and people. I did meet a few nice people... on the boards, too. Mostly I came away shocked at how mean and reckless some human beings treat others. Scary and enlightening.
