I think there's a big caveat to these user stats. I think it only considers who last edited the node or way masking the original contributor. Plus, deletions, merges, and splits are not considered.<br><br><br><div class="gmail_quote">

</div>It sounds very encouraging, particularly the number contributors that have at least had a go.<br>
<br>
Even in the UK, which must have several thousand contributors, I believe a study last year showed that 80% was contributed by just ?40? contributors.<br>
<br>
If easy to do, it would be interesting to calculate what percentage was contributed by, say, the top 5 contributors. The lower that figure is, the more folks other than the original core contributors are getting active.<br>
