I agree that the issues the OP brings up are problems -- at least from the perspective of a single man -- but I'm not sure these are problems with online dating so much as dating itself, or the world. The male:female ratio is a problem in most dating settings, for example. In terms of whether online dating needs "fixed", I'd be interested in knowing how the success rates for online dating are better or worse than current offline methods (going clubbing, dating co-workers, whatever). My own worthless anecdotal experience shows a much higher rate of success in online dating than trying to meet people IRL. ("Worthless" because I met my wife online, and we naturally hang out with people who tend to spend lots of time on computers.) Also, from the OP: I had average success on this service, but the reason it probably wasn’t better had to do with the fact that the Q&A section tended to expose character flaws that turned me off. I think it's interesting that the OP was getting too much information about his potential partners... or at least, too much too early. Most people have flaws, and one advantage of traditional dating is that you learn about their flaws more slowly and have time to learn good things that mitigate them before getting scared off. However, I think it's more likely that people are going to have to adjust to knowing more, rather than using services that expose less: more and more we live our lives online, and it's very easy to learn "too much" about someone just by using Google. We're either going to have to accept that people are flawed, or it's going to get even harder to find partners...
