Wikis
I do look at and use the Materials Management wiki on a regular basis. I was on the Reference Resources Committee this past year and the notes from that committee are posted here. I do like getting an email notice when it is updated so I keep aware of what is on that wiki.
I did use the Long Range plan wiki to post comments a few times during that process. It is good to have a place to go to check on current happenings.
I also use the New Tech wiki once in a while.
Last summer I created a wiki to use while planning a training workshop for a conference. This was a great tool for the 3 of us to use since we live in different parts of the country.
Wikis need to be kept current to be useful. Once the conference is over or there no longer is a need for the wiki, it can be deleted or not updated.
Wikis can be simple or complicated, depending on the need and on the expertise of those who are creating and updating it.
