Atlassian keeps it at $10 for 1-5 users. Awesome!

And they give the source code to commercial and academic customers for customization.

Transparent pricing. They may be the least enterprisey of the enterprise vendors. :)

There will be a maintenance contract - there always is with Atlassian.

[luser001]

will be meaning mandatory? No, there isn't.

I've downloaded and used the 5-user version of the wiki (Confluence) and I didn't pay anything more than $10. I expect this to be the same.

The moment it breaks you will need one...

The maintenance contract is another $10 for the next year (assuming you're still < 5 people). And you get software updates during that period. It's not particularly devious.

Well does your Windows XP breaks? Does it still work? Of course it still does, but you will have to pay if you want the new stuff.

[luser001]

It hasn't broken for me. And I don't expect it to. YMMV.
