I'm not really happy with the state of online dating sites these days. I had a successful relationship through one ten years ago. These days, they are too expensive, keep too many profiles of people no longer looking, have a higher rate of scams, and less tools for really meeting successfully.
That being said, Zoosk is one of the better sites today. I was still targeted by a scam, in which we held a normal conversation for about a week before they tried asking for money. So be aware, it happens everywhere. I did meet my current girlfriend on Zoosk, though only the initial hello. She did not buy a subscription because of the cost. There's a lot of room for improvement, but it's still one of the top 3 sites you can use today.
