While checking my Mint stats this morning I ran across a link to LesserWiki, a Ajaxified Ruby on Rails Wiki that looks promising.
I noticed right away that the wiki's page seems to keep a read history appending the latest article to the top of the page. The downside; there is no back button so until you realize what it's doing it there is a little bit of confusion.
I'm curious if anyone has used it in a production environment and if so how does it perform.

Yes, I thought it looked promising too. I used to host lesserwiki.org, and really enjoyed working with Yatsu. But he moved on, to a VPS setup, I believe... (Don't get any ideas... ;-)
