I am looking to set up an internal wiki for our development/design team.
The key feature I am looking for is a very simple editor with revision history. Ideally, the uber-simple markup system StackOverflow.com uses (Markdown) would be great. One of the reasons for this is that we have non-technical people (managers, sales people, designers) who would benefit from a clean markup, not having to know HTML, and yet still be able to view revisions and make modifications easily.
I have tried ScrewTurn Wiki, but it seems its markup is very ugly, and thier latest WYSIWYG seems kinda buggy (keeps adding lines on revisions).
I would be willing to use a non-.NET solution if it provided a turn key solution. I would just prefer .NET since we are a .NET house.
