First, the range of greens used by Mapnik! It's great to differentiate, but I don't think we've yet cracked the balance between this and making it clear. The map key is pretty revealing - you need good eyesight to find the corresponding shade. It's not just greens, either - we use lots of area shades, which is attractive and useful once you know what they mean but with so many shades it's very confusing. Second, label placement again, but specifically getting more of them into a space. Mapnik uses a pretty primitive collision system, so whilst there is often loads of space to squeeze in names they get left out. A human would have no problem labelling all of the amenities on this map view, for example: http://www.openstreetmap.org/?lat=51.38&lon=-0.1544&zoom=16 Often road names are placed in the middle of a way, cutting out a pub name when the road name could just be placed a little further along. Or a road ref stops a place name rendering, which again just needs to be moved around a bit to fit in -- place names aren't so precise that a 100m correction at zoom level 14/15 will matter that much. Other maps like A-Z seem much better at labelling everything.
