Funny story: Atlassian is an enterprise wiki used all over the place. It’s built on Java.
Atlassian’s role in this? They are building a Sharepoint connector. Why do that? After all, Sharepoint has its own wiki service?
Cause Atlassian’s is better and Microsoft’s customers were asking it to support Atlassian’s.
Anyway, I’ll have a video up with Atlassian talking about this in a few minutes.
UPDATE: Here’s Atlassian’s blog talking about the connector.
UPDATE2: Ross Mayfield, founder of SocialText, reminds people that his wiki product was partnered into Sharepoint last year.
