Any good collaboration software?

Preferably something that can be run on Linux.

We're currently looking at http://twiki.org/ , but i'm wondering if there are any better ones out there that people have had experience with.

I've installed twiki at my office and our developers seem to like it.

http://www.wikimatrix.org/ Pretty good comparison site for most of the wiki's out there...
