Milwaukee.
The final AoIR 2009 session for the day is on Wikipedia (hmm, so few papers on Wikipedia at this conference - why? just because Twitter is the Next Big Thing now?). We begin with Lindsay Fullerton, who notes the trends in Wikipedia which have been able to be observed over the past few years. In particular, edits of Wikipedia policy texts have substantially increased over time, to the point where there is now more work on Wikipedia policy edits than on actual articles; additionally, of course, there has been a massive growth of Wikipedia editors, levelling off now and standing at around 180,000.
