Thing 12 Wikis

I am not a fan of Wikis. I attended a summer training a few summers ago where our group project was completed on a Wiki. One person monopolized the entire project and would change what we posted on the wiki. I do like Wikipedia for some things I am looking for. Sometimes it is actually faster to find very current info on Wikipedia however, the problem of course is the info hasn't been peer reviewed. I have used PB Wiki in the past.
