[OSM-talk] Why do we have so many registered users with zero edits ?

Mon Apr 15 04:24:03 UTC 2013

Not quite sure what Werner wanted to convey with the info about the shape and numbers of the long tail of OSM (perhaps nothing more than the numbers).

Anyways, I'd just want to say that the "tiny" 0.1% of the data might well be a huge number of otherwise missing POIs, place or road names or other map features' details, tiny corrections to roads, etc.

It's also likely a thing that has made 100+k people love OSM just a bit more.

Suddenly 0.1% isn't that small anymore.

Cheers,

I think the quotet 220000 are those mappers that still "own" an active
osm object. (last editor).

http://www.h-renrew.de/h/osm/osmchecks/03_Statistik/planet/statistic.html

statistic based only on the last editors.
about 25000 Users only own a single node.

90% of all ways and nodes are last edited by about 7000 users.
99% by about 30000 users.
  --> 9% of data, 23000 users
99.9%  80000 Users
  --> 0.9% of data, 50000 users
and the rest:
  --> 0.1% of data, 140000 users

Regards
Werner
