"... 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

Yes, it's often that people think they edit a map, but in reality they edit
a database -> resulting in several very different maps.

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