We use wiki from earliest stage as a repository for all sorts of information. We don't go out of our way to get fancy it, though, so we don't need a lot of advanced/refined functionality.

I've been through this cycle a few times, this time we are using MediaWiki. I don't remember what we used last time, I think it was a Drupal-based wiki.

None of them made a whole lot of impression on me either good or bad.

I agree w/the other posters that this is a pretty ambitious goal ("better wiki") - I'm like a lot of other folks in that what is out there is more than enough and we probably don't even exercise 10% of the features.

I also agree w/the other poster that said "people don't bother". Very true, stuff usually doesn't end up in wiki unless I put it there or I ask somebody else to do so. Very few people will do this habitually without a lot of strong and recurring encouragement.
