Idea: a map app with the interface of a dating app. I want to see and quickly filter all coffee shops in my city. I open the app, I start swiping. There are hundreds of them. I won't get through all of them in one sitting, but I don't want to see the ones I've already swiped away.

Frankly, I could use that app for TV/movies too. No, Netflix, I *still* don't want to watch "White Chicks", please stop presenting it to me.
