what to do with a wiki?

I enjoyed Lee le Fever's video on Wikis, especially because I recently arranged a simple night out with two other people and it took a huge number of emails. It is interesting that his approach to the way to use wikis seems quite different to the way wikis are actually used. He takes a simpler approach that may just be for the sake of example.

In terms of the State Library I can see wikis being used to highlight events and new resources. They could also be used to gather information about items in our collections such as we've seen with other organisations asking people to add info about photos. Their could be a role for wikis (heavily moderated) as a way of recommending resources for various collections (such as Infocus) and specialised websites.
