I love Stack Exchange-like sites. I think they have found the way to really make people addicted to helping others :) These sites work well for general "fields", such as programming or system administration. Raspberry Pi, however, is a much narrower field and also has a much more close-knit community.
I would like to discuss whether the Stack Exchange model (explicit questions and answers) is suitable for such a field. Forums (à la phpBB) allow free expression/original research/..., while SE-like sites is a more limited way - you have questions and you have answers. Not everything is a question or an answer. Sure, you can express your ideas as an answer to an artificial question, but that is a bit awkward.
What do you think will be the role of Raspberry Pi Stack Exchange? Will it replace the official forum as a primary meeting point of Rasp Pi users?
