"... People think they edit a map, but in reality they edit a database ..."
When I was a complete newbie - not long ago - it took me a while to realise this. It is an important point and once I had cottoned on to it I understood the philosophy and practice of mapping and tagging much better. Perhaps the concept should be given greater prominence in the wiki - especially those bits aimed mostly at newbies. It helps to explain many aspects of what the more experienced mappers and taggers seem to be doing.

And that's much better than other people removing stuff without asking first ;-) > I am most used to the USGS 1:25K paper maps, and at that scale there > is a sense of clutter vs useful.

Yes, it's often that people think they edit a map, but in reality they edit a database -> resulting in several very different maps. > Driveway has a connotation of private road that one should not be on > unless a guest of or going to the place at the other end.

The access tag makes perfect sense here, especially access=private when there's a "no trespassing" (or alike) sign there.
