Hello all,

I have written a blog post on preferential attachment. It could interest you:

http://www.samarkande.com/blog/2008/10/09/wikipedia-et-lattachement-preferentiel/

The post is in French, sorry; but you will find in it links to Englis pages like this one: http://en.wikipedia.org/wiki/Wikipedia_talk:Wikipedia_Signpost/2008-08-11/Growth_study

And here is another link concerning participation (by the famous Jakob Nielsen): http://www.useit.com/alertbox/participation_inequality.html

Cheers,

Regarding this, I have had heard different stories about contributors.

I seem to recall one study that concluded that, while 85% of the **edits** are done by a small core of contributors, if you take a random page and select a sentence from it, this sentence is more likely to be the result of edits by contributors from the "long tail" than core contributors. I forget the reference for that study though.

Does someone on this list have solid information about this? I think it's a fairly crucial piece of information that we should have a clear handle on as a research community.
