Confluence at Sun AND IBM [updated 21/09/07]
You see - Confluence *DOES* rock. Check out http://wikis.sun.com and take a look at the bottom right-hand side of the page. No shonky knock together wiki here 
Also turns out that IBM use Confluence at Developerworks too - only it’s less obvious that it’s Atlassian’s product. It looks the same and even tastes the same if you lick the screen, but it’s not until you view page source that you’d see it.
