Here is something I can find a purpose for in my life as a librarian. I have tried to set up wiki once. Not much happened. I have set up two for my classes and those worked fine. So, for my own use these are not a effective as I would like.
I checked out a couple of wiki set up by organizations and those seem to be useful. I liked the wiki set up by librarians , one was by ALA a best practice wiki and another was the one set up by Oregon Library" Library 2.0". Those offer good ideas in how libraries can use wikis.
I also liked the Wetpaint wiki but my problem is coming up with names for these. My imagination does not go beyond the basic names. I will take some time to set this one up.
