A few thoughts.
In my experience, Wikipedia is a place for finished articles, even if
they're small. At least to the point that they can survive the assorted
bots and reviews while others enhance them. Developing articles for
Wikipedia would be a limited purpose for a SIKM wiki. Posting stable
content that we develop that seems appropriate for Wikipedia would be a fine
secondary purpose.
There's been some recent interest about "life cycle management for
knowledge. Developing criteria & indicators for such seems a good
purpose for setting up a wiki-based discussion. As other questions or
issues arise, separate discussion pages could be added to a SIKM
wiki.
I've worked with both Yahoo and Google. Yahoo doesn't host wikis and
group exchanges won't work for this purpose, so that's out. I've seen an
awful lot of garbage on open Google sites, so if we use Google, we should keep
it for SIKM members only AND have it invisible to the general
public. Google wikis are intuitive and easy to use. I
could easily set one up, but they seem to be linked to organizational
domains. If yes, that won't work here.
I have used another free wiki site that I will investigate this afternoon,
although it seems to have some firewall issues and is more
difficult to use than Google.
