This looks like another seriously interesting piece of work.
Mart is putting together a “wikipedia” like solution on SharePoint.
I have a lot of time for Wiki’s, our support team use one (based on Flexwiki) to maintain an Engineer Guide and it works really well with information kept really fresh. I’m looking forward to their development (editing difficult for average users) and I see them being a key piece of the collaboration pie.
This week I’m going to test it out, would love to see our Engineer Guide hosted on a SharePoint Wiki!
