“Dating Sites”

Has anyone tried the various “Dating” sites. Okay, so I really mean hookup websites. I’ve not found one I’m willing to put any money into. I found cityxguide.com the other day. To me it seems like you can spot the fake profiles a little easier. I contacted a couple of them. I received a response from a few of them. Two seemed legit, set up a meeting with one at a restaurant, I was buying dinner. She didn’t show. Another, got a response, but as the conversation went on, it seemed like she was trying to get me to ask or say something, I had an idea of what it may have been but I didn’t bite. So, just curious, has anyone tried anything like this? If so, what were the results?
