Kii is a young and open source Rails powered wiki. I started this
project for two reasons.
1. Whenever I need a wiki, I end up using something that isn't
Rails based. The existing Rails based wikis has strange
codebases, is outdated, and generally isn't very nice to work
2. Wiki systems tends to look like they were made in 2001. No
Kii sets out to fix this. The codebase is at the moment quite
sensible, and I tend to keep it that way. The preview interface
(http://kiiproject.org/Sandbox/edit) does not look like it was made in
2001, either. AJAX, wohoo!
There's still a long way to go, and the http://kiiproject.org/Worklist
is pretty long. Accepting contributions!
