I think it's great that you're being honest about who you are. I definitely prefer a somewhat descriptive profile to nothing.
I think the fact of the matter is that maybe the type of women who you might click with for more than friendly online chat just isn't on this site. I've been on this sight for a while and haven't met anyone through it for more than just online friendship (even though I wasn't really on here for a year or so while I was dating my now ex-bf). At this point, I'd be shocked if something more happened through this site.
In response to women choosing looks over personality: In reality, we women want BOTH!! There HAS to be some physical attraction between two people. Online, it's NOT an option because all you have a pictures to go off of initially. Reading about someone's personality isn't the same as knowing or seeing the person first hand. The advantage of, say, getting to know someone you go to school with or work with, who you might not have otherwise gotten to know, is that even if they're average in looks their personality can totally make up for it. That luxury just isn't there in online dating/networking sites.
On the same note, what you think is attractive and what the next guy thinks is attractive can vary to great extremes. I have been attracted to
(1)good looking guys
(2)average looking guys
(3)guys where I wonder why I'm attracted to him (not because he's ugly, but just because I can't figure out why I'm attracted to him.
Like someone else said, online people typically just look for a picture they're attracted to and then if they like what's on the profile, THEN they might try to get to know the person better... not the other way around.
Best thoughts to you in finding someone who clicks with you, whether on here or elsewhere! :)
