#16 Wikis

Wikis are good for collaboration.
Although I was part of a study wiki for 20 weeks last year, it's good to see the common features of other wikis, and read the background to them.

There are three ways of sharing information that come to mind: wikis, forums and blogs.
Wikis have the article or main page separated from a discussion page. This is good.

Blogs are more time-bound. I think they'd be not so useful for eg exploring a library collection.

Not sure about forums. Perhaps heavily question-based?
