I had this exact same idea about 8 months ago - connecting singles around events. I was a little more focused on bringing local businesses into the mix to promote the events though. I thought through it quite and bit and my conclusion was that it doesn't really differ much from a singles night. An app that made facilitating a singles night easier is a pretty solid idea, however, selling it as a dating website is not the right way to go in my opinion. The main demographic for dating websites has always been men. The problem with trying to put together a singles night is that the main value proposition (women) is difficult to come by with an online dating website. Additionally, a lot of people who try dating websites are there for a few main reasons: 1) they are too busy to go out and meet people 2) they are too shy to go out to meet people. Either way, this solution doesn't solve those problems. I actually built out a good portion of the backend of this product but have since pivoted into something different. They also will run into the chicken and egg issue, although with a little facebook marketing that's pretty easy to solve.
