I don't think more loser men (or women) come to online dating than in real life. I think that your chance at finding someone to date is difficult no matter where you go. After all, is it really more likely that the guy or gal is a great match by meeting in a bar, mall, other public place than it is online? You know just as little if not less than you do with someone that presents a profile up front. Sure they can be lying in their profile but just the same someone can pretend to be something they are not in real life too.

It is true that Online dating in general presents its own unique problems that are due to the nature of the online world but it's neither worse nor better, just different.

I think that trying out different dating sites isn't necessarily that one is better than the other so much as at any point in time, there are always fewer good men and women to meet than their are those that have less than pure motives. It's a matter of patience in either case RL or Online.
