I know a few of you use DokuWiki in their company. A german student from cologne is writing his diploma thesis about Wikis in Enterprises and is looking for data at
http://www.wikipedistik.de/survey/
The survey adresses enterprises of any size and also enterprises not using a wiki. It is held short on purpose and answering it will take only 5-10 minutes at most.
With your participation you help building a data pool allowing conclusions based on which it is possible to evaluate the use of wikis in enterprises and to compose recommendations.
Everybody: take your time and help him, and if you know someone else using a Wiki in their company send the link.
The survey will end in 10 days so you need to hurry ;-)
