[HOT] Improving the quality of OpenStreetMap Data

[Martin Raifer]

Hi.

It is correct that iD hides features if there are too many to be
displayed, but when it does it also prevents mappers from using the
presets which are currently hidden. Because of this and the fact that
it is very difficult to actually map a building in a zoomed-out map
view, I think it is unlikely the root cause of buildings being
remapped.

This probably explains why there are so many duplicates.  Although one should zoom in much further before mapping buildings to help ensure accuracy, this is a significant flaw in iD in my opinion.
