I like Wikis. I think they are easy to use and practical. I had some experience with PBwikis in one of my courses. I remember having to put a library budget on the wiki. We used a table copied from word. The formatting was tricky but I think that just for basic word processing a wiki is a sufficient tool.
I looked through the websites and can I just say, is Meredith Farkas everywhere? She created the Library Success: A Best Practices Wiki. I have read her name numerous times since I started this LS program. She is definitely a mover and shaker in the library technology world. Anyway, I really liked the her wiki and added it to my Google Reader. I also need to look through the list of library blogs available on Library Bloggers Wiki. The list is extensive! In the TeacherLibrarian Wiki I read about a librarian that offers a Books ala Carte services. That is an idea I will tuck away and hopefully use someday.
I can see that one of the most obvious uses for a wiki in a library would be for book discussion and reviews. As far as the classroom, I would setup one like the Westwood Schools teacher, Vicki Davis has (one of the samples posted in week #7). Her wiki is not just for special projects that are here today and gone tomorrow. She definitely has a lot going on in her wiki and makes it an active part of her classroom. It has won many awards.
