This is why I still like standard discussion style forums as opposed to Question/Answer forums like StackOverflow. Yeah, if you have a very clear and specific question and want a clear and specific answer, SO works. But, it doesn't allow for the give & take and interaction that can provide for a wider & deeper learning experience that the discussion forum allows.
