I met my OH on a dating site- we are in process of buying a house together.
2 of my other friends likewise, one is now married as a result, the other is engaged..
I agree i met some wierdo's, liars and guys after sex, but being honest, havent most of us met guys like that out "in the real world" too? I've met more than my fair share of such in bars, clubs, parties and even work.
So, be open minded, by realistic, be alert, be cautious, and dont rush into things..... and trust your gut instincts!
I did try a number of dating sites and they do vary- some are really geared to a slightly, umm, down market audience- lots of txt spkrs on it. Some seem to get players, but i eventually found 2 sites that i liked the approach of, so its a case of looking around and finding the one that suits you.
