Some of the articles posted here from OK Cupid indicate that an awful lot of deception goes on there. Average reported heights are two inches taller than reality. Average reported income is higher than real averages. The most attractive photos are older on average than other photos on the site and were typically older at the time they went up. Most people who list themselves as "bisexual" don't actually chat up members of both sexes. Genuine, intimate relationships require a certain degree of honesty that dating seems to actively discourage.

I read once that people are generally more honest online than in person. I don't know if that applies to dating sites or not but I've heard plenty of stories that indicate people are not terribly honest when going the normal dating route either. People who get to know each other socially (through work, hobbies, etc) before getting romantically involved seem to typically have better relationships. Hopefully this site will offer something in common to base a personal connection on and give people a good place for starting a meaningful conversation. The fact that both parties are looking for someone else is usually not much of a conversation starter.

EDIT: All of which is beside the point. My only point was that I am not a fan of dating sites and even I think this is a good idea. I added a little bit of why I think it's a good idea in hopes that it is useful information for the site owners. I don't see why that merits a downvote or reactionary comment.
