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: 9
wiki pages: 313, which is a 50% increase over the past month's 205
Progress has been a bit slow as we deal with some issues. The notification system still has some problems and we want to get those fixed before we start pushing too hard.
We are still suffering from the wiki's failure to show the changes to the wiki page as part of the notification. [See Sharepoint Wiki Disaster.]
