//SEIBERT/MEDIA (http://www.seibert-media.net) is a German web agency with over 60 employees and experience since 1996. We started to use our new wiki in July 2007 and have been experiencing a tremendous usage increase and a lot of successes, that I would like to share. Additionally we have collected a couple of good insights, on how to sell a wiki both from an economical perspective and an internal perspective to clients.
