open spot

so i just downloaded this app. cool concept in a way but you cant clear the mark open car parking spot. what if you mark it by accident? which i did by playing around with it. LOL it should have been a layer on the map with actually coordinates. and you can mark the same spot as many time as you want to earn 'karma' points. kind cool but lame at the same time.

Does "Karma" do anything for you?
