I’d tend to agree with Gartner on this one, wiki’s are on the move in the corporate world. Within IBM, anyone can create and manage a wiki but, I think the tooling will need to advance significantly (and 4 years is plenty of time for that) and the older generation who are not avid technology adopters will need to die off. The current generation just expects this stuff to be there, so there is no adoption issue for them.
