I've tried a couple of different dating sites--eharmony and match.com and a few others--and I had by far the worst time on chemistry.

First of all, they're dishonest. They do the bait-and-switch deal that other sites are also known for--luring you with someone really good-looking and interesting who then turns out to not be active or perhaps not even real. I signed up one time for a free trial, and what do you know, I was matched with this too-good-to-be-true guy named "Jorge" who, get this, said he was "interested" in me. He had a good job and wasn't too old or too far away from me ... I was suspicious--not because such guys don't exist--but because, in my experience, they don't exist online. Well, I decided to throw down fifty bucks anyway, what the hell. I reciprocated his "interest" ... and nothing. Not a peep. Never heard from the guy again. It became clear that he wasn't active and probably hadn't sent the "I'm interested" message in the first place.

The other guys I were matched with were closer to what you'd expect--unattractive. I'm sorry, but these had to be the ugliest guys I'd ever seen in my life. Well, I'm not shallow and believe that true beauty is inner, so I chatted up one of them, sent a few emails, and went ahead and arranged a date. Bad move. Worst date of my life. The guy ended up being a creepy loser still living at home with his parents, etc. etc., and that wasn't the worst of it. The quality and subject of our "interaction" drew some pretty strange and amused stares from the patrons around us. I fled from the Starbucks after 20 minutes.

My other matches on chemistry were pretty much of the same quality--unattractive, socially awkward guys posting their college portraits as their profile pictures. I cancelled my membership after a month after not hearing another word from "Jorge."
