Thing 10: Wikis:

This is a very different place! Anyone can contribute, change, and add to a wiki. Most websites can only be read. With their knowledge-sharing tools, Wikis are great for libraries. The Library is a collection of organized information, resources and services. With the collection of media other than books for storing information, libraries now offer access points for maps, prints, and other documents on various storage media. Wikis are easy to use, are web based and great for group projects. Wikis are full of potentital, and are free and open publishing systems. Everyone is encouraged to share information in their areas of interest and expertise.

I experimented with editing the 23 Things on a Stick Wiki.
