Jonathan Boutelle talks about how he made a wiki work with his software developers:

• Start off maintaining existing documents
• Make it easy to login
• Insist on Wysiwyg

So, so true. The first two could be a little more generalized: Start with a reason to use the wiki and make it easy. Making it easy encompasses insisting on Wysiwyg but the editor is the most important touch-point of a wiki that it's worth stating separately.

I've previously commented on this kind of thing before, so it's good to see others learning the same lessons. Of course, I'd suggest using a really good editor like EditLive! for Java, but I am somewhat biased…
