You could pick out your most trustworthy friend and have them review your profile and see if there is anything that could be turning off prospective matches.

Fuck those sights, reality outside the internet is how you meet someone. Go hit a bar or a bookstore, coffeeshop etc. Compliment someone on the street, and see where it goes. No offense to your efforts but technology is dumbing us down to do things a specific way and dating online has worked for people but what happened to having some backbone, approaching a woman and paying her a sincere compliment and asking her out? Anyways, goodluck in your quest.
