Mark Crane posted a link to something called pbwiki.com to the Tech-Rhet mailing list. The “pb” part of things comes from their motto/catchphrase: “Make a free, password protected wiki as easily as a peanut butter sandwich.”
I haven’t quite figured out what I would use a wiki for in my teaching, but I did set up a wiki with this site in about 3 minutes, which strikes me as being kind of a good and cool thing.
Wikis are a really great way to archive and interlink information on the fly. I used a Wiki as my personal information manager, simply because it’s SO simple to link data and create pages.
