Something I wanted to know for all your examples was:
Which Wikis detect overlapping/simultaneous edits of pages?
The last time I tried Kwiki, it didn't. One person could start to edit a
page, a second person could start, edit, and end the edit, then the first
person would save and the second person's changes would be completely
wiped out with no warning. "Last person to save, wins."
I also echo the comment by the person who said you should use your
evaluation criteria for *all* your wikis examined. You often only
mentioned one or two of the criteria, and you don't quantify how
well each wiki rated for each one. Good start! More details!
