Or don't represent height at all, just show all buildings as slightly extruded 
like in the shot Artem provided. Then it conveys "ooh, it's a building" 
really well (I love it) and you don't then think that building is 15 metres 
high just because Mapnik uses the default of 15.

On the default map, anyway. If people want to gather height data for their 
area then they can do that and go all the way with accurate representation of 
dimensions, shapes, etc. in their render.
