Staff Wiki

I enjoy adding things to our wiki. I have contributed to and relied on the information in the knowitnow wiki. Wikis are my new rolodex. They are a large well-organized favorites list. I want to create one for the Gahanna staff but I am not sure how it work. What information could be put on it and what couldn't? Passwords couldn't, but most other things we keep in the reference desk notebook could. What about the rolodex? It contains a wealth of information that was updated until a year ago. If it was in wiki format, would we use it? Would it be too annoying to have to go one more place to check for updates and information? Daily news like assignments and displays and popular questions are conveyed easily enough verbally as we switch on and off the desk? Would we use it?
