As the topic of quality is frequently raised on this list, I would like to point out some of our papers. Me and a colleague have researched information quality in virtual communities, especially assessing completeness and correctness. While we have not worked on Wikipedia (We tested for example World66 and Wikitravel, wikis for travel information) the methodology we used can easily be transferred to Wikipedia. We claim that it captures the user perspective in a rigourous way.
The results of these studies were encouraging: virtual communities - without monetary compensation - are capable of getting even with comercially produced information products. An open question remains about the required minimum activity for a virtual community to create and maintain information of high quality.
I hope this helps and stipulates a discussion. Please do not hesitate contacting me for any questions.
