what can you use a wiki for?

Wikis were one of the more foreign things I discussed at my talk. It’s easy to point to Wikipedia and say “Look, a collaboratively built encyclopedia!” but it’s more difficult to explain how a librarian could use it in their own libraries. Today Teleread has a post about using a wiki for a book discussion group where groups can collectively annotate a book club web site. I think this is what the National Science Digital Library was hoping for with its Annotation and Review Services wiki but it seems to have suffered from neglect. Here’s a neat little wiki about blogs.
