Google Groups needs to switch to a Stack Exchange paradigm. I'm hard pressed to see what the disadvantage would be.

Stack Exchange is designed for one type of interaction: answering focused questions.

It's not appropriate for just putting an idea out there and discussing it, or for that matter even having a discussion about answers to an individual question.

What? The systems are entirely different; they aren't designed for the same purpose and they aren't at all interchangeable.
