I fully agree with these points. I've done a reasonable amount of mapping in
Sittingbourne, but my mapping tends to be centred around highways rather
than landuse or buildings. I have updated some similar tagging to what you
describe on schools in the past such that the buildings are tagged with
building=school and the extent of their grounds is tagged with
amenity=school, rather than the previous building=yes + amenity=school on
the same buildings.
I believe that lots of the buildings have been derived from automated
OS_OpenData_StreetView tracing by OSM user SemanticTourist. That probably
explains why they appear to cover multiple actual buildings in reality and
that they shape doesn't always correspond terribly well to the crisper
buildings you can see in the Bing imagery there. You may have noticed that
the building coverage actually spreads beyond just Sittingbourne to quite a
sizable chunk of Swale borough centred on the town.
Thanks for the work you've done here so far. As far as I'm concerned as a
local mapper feel free to update the problematic tagging as you've
described. I'll probably be able to help out eventually, but am currently
concentrating on getting widespread maxspeed coverage in the eastern half of
Kent and would prefer to get this essentially complete before starting
another large mapping challenge.

Subject: [Talk-GB] Sittingbourne
I was looking at the OSM Inspector, and happened to notice a large red bit
over Sittingbourne , on closer inspection, there seems to loads of good
data for Sittingbourne in OSM. However in my opinion, its not presented
(tagged, ...) in the best way.
The three issues that I have seen are:
- landuse=residential building=yes tags on the buildings
- in most cases this should just be building=house
- building footprints are too big and often cover many houses
- just need spiting up, one house, one building way
- addr data separate from the building outlines
- merge data per 
So, if anyone is having problems finding places to map... Also, if anyone
disagrees with the above assessment, please shout. I have already done a bit
of improvement here .
