I'd do it, I know for a fact that there aren't any prospects for me here, all the girls near where I live are too stuck up or already taken or both. Plus I'm bad at getting to know people through intimate conversation, or for helping them to get to know me. So if I can go onto a site where our personal information is all there, all the cards on the table as it is, why not?
Of course I also think that relationships are pointless, and doubt that even if I was able to get one that I'd be able to keep it. I'm not one to deny that a fun "perk" of being in a relationship is the sex, but it's not like one is required to have the other, or that there are other sites that can set you up for just the sex.
I'll readily admit that the only benefit I see in a relationship is sex and thus it's the only thing I'd want to get out of it, I'm also aware that this might make me a bad person, but I feel justified in my way of thinking.
The point being, yes I think online dating is a perfectly valid option, and I don't see why it can't foster healthy normal relationships as well as "normal" dating can.
