Ask HN: Better than online dating?

We built a web app (www.findfish.at) last week to plot single people on a map (using Facebook gender, relationship and LBS data). The idea came to us one night when we were out in town, going through empty bars and sausage fests...

While we never thought of it as "online dating", a few people have been comparing this with LBS dating apps like Loopt. Of course I don't agree with this because I see our app more like a fish finder for singles - we don't introduce you to a specific fish, just show you where is a good place to drop your line.

Anyway, I'm interested in some informed and unbiased views on this. Is this app the same as online dating? If not, do you think people would find this useful/entertaining?
