Of course, there are successes and failures just like any other forms of dating.
True. I've certainly met complete duds online too, but I think with a bit less frequency than meeting guys in bars and such. If you're not a church-goer, so aren't going to meet people through those sorts of functions, are are past school age (of whatever level), so aren't going to meet like-minded people there, it's hard to find venues to meet single people with things in common and a way to get to know them enough to decide they're worth dating. I started out as a total skeptic on the whole internet dating thing after looking at profile after profile and thinking, "Ewwwwwwww! No wonder they're still single!" But, then, I think the same thing when guys hit on me in bars too. And, then I stumbled across someone nice while not even looking to meet anyone, and that's similar to meeting someone nice who just happens to cross your path in any other venue. And it sure works better than having the meddling relatives trying to set you up on blind dates!
Oh, and not everyone I know who met online met through dating sites either. Some of the people I know have met through forums where people with similar interests will gather.
Of course, you do also have more cases of people pretending to be someone they aren't that you have to watch out for. Not just the guy in the bar who says he's a doctor when he works as a construction worker, but the person with photos of an attractive woman who isn't even female, or who doesn't match those photos, or who does a mysterious disappearing act when you suggest meeting in person. People can lie about things about themselves in person too, but not to the same extent that they can pretend to be someone completely different as they can online.
Talking to my friends, I'm learning that more and more professional women are looking for dates this way, so I would assume (or hope) more professional men are using this approach too. They're the ones who don't have time or interest to go hang out at a lot of bars and clubs or church suppers just trying to meet up with someone to date. You can apply simple filtering criteria like, "Can he string more than two sentences together, and use words with more than two syllables?" or, "Did anything in his message indicate he bothered to read past the photo?" (I get a lot of those messages on OKCupid too, and they just get deleted.)
