writes "We are a research team at the University of Wuerzburg (Germany) interested in the reasons and motives why participants are involved in Wikipedia as authors, administrators, or software developers. We hope this study will provide statistical data and insight about Wikipedia which go beyond previous reports in the media, encourage a helpful discussion between participants and reveal best practices for Wikipedia as well as related Open Content projects.
We would like to invite everyone who contributes to Wikipedia at least once in a while to take our online survey. The questionnaire will be available until August 3 at http://www.unipark.de/uc/wikipedia/.
The questionnaire is in English, but participants from other Wikipedias are especially invited to take part as well. Your responses are extremely important to us, and thank you for your time!"
