Getting actionable user feedback is something we struggled with at Aha! too. We experimented with different techniques but what we kept coming back to is that if you ask people directly, and engage them in a conversation, you get the most useful feedback.

Just knowing that someone is satisfied, or unsatisfied, with your product is not actionable. Often the reasons why a customer might be unsatisfied are subtle and would be impossible to discern with a questionnaire or survey. We think the answer is "empathy sessions" - kind of like focus groups meets modern online communication.
