In early April we rolled out Sharepoint 2007, upgrading our intranet platform from SharePoint 2003. I have been keeping track of the number of wiki pages and wiki libraries.
As of today we have:
wiki libraries: 8
wiki pages: 205
Progress has been a bit slow as we debated the wiki structure and security models. The notification system still has some problems and we want to get those fixed before we start pushing too hard.
