University of Minnesota Report on Wikipedia Authorship and Vandalism

From the press release:

"An ongoing study by University of Minnesota researchers has revealed that only one-tenth of 1 percent of Wikipedia editors account for nearly half the content value of the free online encyclopedia, as measured by readership. In addition, the computer science and engineering faculty and students have discovered that few edits inflict damage on the content and damage is typically fixed quickly.

The results of their study are reported in the academic research paper titled Creating, Destroying and Restoring Value in Wikipedia."   [RJ]
