What's that? You're a sucker for any new product from the Google team, no matter how pointless? Me too!
Should I be slightly ashamed that I am such a Googlite? Maybe. Will I show you Frappr! anyway? Yes.
So the idea is that you can join a group and add your location. For example, say you browsed to the Privatjokr Frappr! Map, you would have the ability to see where certain jokers hang their hats (by zip code only) and add yourself as well.
Before you know it, we could have three whole dots on the map; me and my two readers. (I love you mom and dad.)
