[OSM-talk] Who contributed most?

[Lars Aronsson]

In the discussion about the license change, somebody mentioned the 
idea that we might have to delete contributions by users who 
refuse to agree to the license change or by users who we fail to 
contact.

I have no idea if that suspicion is real or not, but it made me 
think: Has anybody tried to estimate the size of contributions 
from an individual user?  Only counting the number of edits 
doesn't say much, because a user can make many small edits to 
convert roundabouts from squares to circles, another user 
contributes streetnames to an already mapped city, a third user 
has mapped the country roads of an entire county.  We sometimes 
hear that OSM has 100,000 registered users, but many haven't 
contributed much.  Well, how many have contributed much?  Who 
contributed the most?  For a particular region, such as Sweden, 
who are the 20 or 200 most valuable contributors?  Do we know?

I think this has an interest (or at least curiosity) on its own, 
quite independent of the license change.
