Glad to know that there are tracking tools within wikis as I never paid attention to them before, as I still have misgivings when using wiki info. Since anybody can post anything, you would hope the info would be accurate.
I checked out all those wiki examples listed. Most of them apparently have the same layout (using the same software?) as Wikipedia that I am most familiar with. Yet it might be a bit boring, compared with “Using Wikis to Create Online Communities.”
As for library applications of wiki, really need to think about it.
