I was a Confluence fan back in the old days and championed its adoption in a number of customers. However, given the recent developments, I can't justify the price feature-wise anymore. And regarding support, I'm still eager to see how they take the blow from www.mindtouch.com, for example. The extensibility appeals directly to big customers with in-house development capabilities. Finally, it will be interesting to see who fills the enterprise semantic wiki space. Not an easy one to do. I have developed two semwikis, so I have an idea of what it takes to get there. It's all about power users... they are not that power yet. ( what does Office integration tell ya? ). - Aldo Bucchi from FriendFeed MT Plugin

@Sarah: Thanks for the excellent and accurate coverage of Confluence 2.9. @Aldo: I'm sorry to find that we've lost an old supporter. I'm interested to hear more about the 'recent developments' you talk about. The pace at which we've been producing new, useful, user requested features have really been appreciated by the bulk of our customers. We're proud to have 6000 Confluence customers this year (up from ~3700 last year). What has really been driving Confluence development is ease of use. This invariably leads to increased adoption. We see adoption, encouraging all users to contribute and find content in their wiki, as our key mission. We know that extensibility and our thriving ecosystem of addons and contributing developers (please see http://www.atlassian.com/softwar...) is an important reason why people love Confluence, but the majority of our customers don't massively customise Confluence. They buy Confluence because <strong>it just works</strong>, and because they can trust our - Adnan Chowdhury from FriendFeed MT Plugin
