[HOT] Improving the quality of OpenStreetMap Data

[john whelan]

I think iD is fine in it's place but it doesn't seem ideal for mapping
buildings by in experienced mappers.

It's developers have to balance machine performance, bandwidth used and I
suspect it was originally designed to simply map highways and rivers which
it does well.
