I just posted on by blog at

http://www.gnuband.org/2011/03/23/paper_wikipedia_research_and_tools_review_and_comments/

a post about the draft paper “Wikipedia research and tools: Review and
comments” by Finn Arup Nielsen.

It is a 56-pages resource highlighting key areas of research for
Wikipedia (with citations to relevant work already published).
The cited papers (with annotations!) are 236!

You might want to check it and maybe involve Finn in the effort of
aggregating the literature relevant to Wikipedia research.
Take care!
