We’ve been using the SharePoint wiki for some time to provide our KM platform within Ciall.  Out of the box functionality may not be considered the most sophisticated – but we’ve found the product useable, useful and scalable.

EnduserSharePoint has a great review of the SharePoint WIKI: Wiki-in-the-Box – Is SharePoint Wiki Really that Bad?

The posting gives a good feel for the inherrent functionality of the WIKI as delivered and the additional functionality associated with its being part of SharePoint.  Good article and goes some way to balancing the books.
