Agree with most of what you say, just the name "trolltag" implies that
someone was doing this in order to disrupt when often no negative
intention is involved.

Yes, with one exception - if a building has been demolished but is still
visible on the aerial imagery most commonly used in the area (usually
this will be Bing), then - at least until we have a "meta database" that
contains information important for the mapping process - it may make
sense to leave *something* there (perhaps a way tagged only with
"note=the building you see on bing was demolished") in order to ensure
that the building isn't re-created again and again by armchair mappers.
