IIRC the saying is "two wrongs does not make a right".
Original use of tags with the landcover key, that is mappers creating a
new geometry with a landcover tag, is as follows (based on data from
72848 ways/relations (more of half of these created in organized mapping
with tagging not being the free choice of the mapper)
1310 different users
494 of which have used the key exactly once (this, i.e. that about 1/3
to half of the genuine active users of a tag have only used it once is
pretty standard but still this has to be kept in mind when
contemplating such numbers)
The reason why taginfo reports only the number of users who have last
touched features with this key is not because this is particularly
meaningful information but because this can be counted quite easily
when processing a planet file (which is what taginfo does on a daily
basis) while numbers on active users (i.e. who maps features with a tag
or who adds a tag to features) can only be determined from the history.
I can highly recommend Frederik's talk on the matter of OSM statistics
which discusses this in detail:
