'taint a simple comparison, though: Potlatch doesn't set created_by  
on nodes at all, but does set created_by on way updates. JOSM sets  
created_by on way and node creation, but not on update.

I did a few bits of SQL footling around recently on a UK planet and  
it would _roughly_ suggest that more UK edits at present are done  
with Potlatch than JOSM. I suspect the reverse is true in Germany!
