Distance filter that allows you to set max distance:
Club - Profiles under 20 meters
Building - Profiles under 50 meters
Block - Profiles under 100 meters.
Neighbourhood - Profiles under 500 meters

That kind of thing. A quick way to tell if anyone is even remotely close, the "nearby" of 20km is crazy. Especially in bigger cities with multiple bars in the same city block, even customizable distance feature would be nice.
