The abstract says:<br>
<br>
"All three aspects (users, elements, and contributions) demonstrate striking power laws or heavy-tailed distributions. The heavy-tailed distributions imply that there are far more small elements than large ones, far more inactive users than active ones, and far more lightly edited elements than heavy-edited ones. Furthermore, about 500 users in the core group of the OSM are highly networked in terms of collaboration."<br>

So, we should really take care of casual mappers!</div></blockquote></div><div class="gmail_extra"><br></div>I confess to not fully understanding all the statistics in the article, but it is clear that "casual" mappers make significant contributions to OSM. I did wonder about the statement "... about 500 users in the core group of the OSM are highly networked in terms of collaboration." Really, collaboration? Someone just made a mass edit in an area I watch with a user name I didn't recognize. Nothing wrong with the edit, I'm just pointing out that we don't always collaborate. Imports are a good example of when we do and a perfect example of when we don't.</div><div class="gmail_extra"><br></div><div class="gmail_extra">Clifford<br><div><br></div>-- <br><div class="gmail_signature"><div dir="ltr"><div>@osm_seattle<br></div><div><a href="http://osm_seattle.snowandsnow.us" target="_blank">osm_seattle.snowandsnow.us</a></div><div>OpenStreetMap: Maps with a human touch</div></div></div>
