Wikis

I tried siging up for a wiki on two different websites, pbwiki and wetpaint. Both were easy, but I like the templates on wetpaint.
The main advantage for a library to use a wiki for their website is that all employees can post to or modify the page. This means no submitting the information to the IT department and waiting for the information to be posted or worrying about miscommunication. Staff can post, update, or correct information immediately. Patrons can easily add comments or book reviews, also.
I know some libraries use wikis internally instead of an Intranet site. One library I am familiar with posts current facilities issues, meeting schedules, and other information for the staff on the wiki. This seems like a nice option for everyone to keep up with branch issues especially if there is more than one shift working at the branch.
