I think pretty much has been said previously but I think one can easily miss the point. I assume the technology (wiki or document manager) is the result of an evaluation of needs but some people choose technology no matter what is it for. Result is that they implement a wiki that is not adopted. For instance, Sharepoint is an acclaimed solution among knowledge managers and it becomes THE solution for KM. Digging a bit deeper would show that SharePoint is good to store documents, formalised knowledge. It hardly adressed (007 starts to) idea capture and knowledge sharing. What incidentally blogs and wikis do pretty well.
- Wikis and SharePoint are different tools.
The first one is for collaboration on documents in the process of formalising it. It displays the latest version and keep tracks of any modification. Second one is for storing on-line documents. It is very helpful when documents are already stable. If not, wikis are simpler.
- Wiki is now part of SharePoint
That's cool but it is in line with the progressive integration of blogs, wikis, social bookmark and document managers. We see appearing a new form of groupware. And there is currently a dozen of companies doing that.
Trick is that the wiki in SharePoint is very low profile when it comes to be benchmarked with other wiki solutions. The key element for chosing one system of the other is what is the most important stuff you want. If document management is the key element, then SharePoint is relevant. If not, it might be clever to have a look to a different solution.
- Alternative is to build a solution that meets your requirements. Not being bound by technology is the best way to address issues and tackle them. Mixing excellent blogs, wikis, document managers and social bookmarking and tagging and integrating the whole thing in a single interface is a piece of cake. It's also a good element for adoption: users get the best of every solution which renders the experience better.
