I only just realised how lame getsatisfaction.com is:

• You can’t sort search results by popularity
• You can’t restrict search results to answered or unanswered questions

Well, that pretty much renders it totally useless right there, for both customers and companies, unless the community you’re searching is tiny, in which case why would you need the site anyway?

Oh yeah, and the undocumented boolean AND searches don’t work.

Staggering.  (I’m praying someone will tell me I’m wrong about at least one of these.)

Update 2010/03/07: got a reply from getsatisfaction on search results sorting – I was right but there is a kind of lame alternative.
