If you're looking to have someone provide you with all the answers, you're bound to be disappointed. This is a forum where the subject matter is one where we don't have all the answers.
The process of learning is more than just being told what the answers are. The value of this forum lies in working together to try and figure this stuff out.
I'm not sure why you don't think Paul's posts are valuable. He has a knack, imo, for spotting and articulating questions that should be answered before reaching certain conclusions. They are often not easy to answer, which can lead to frustration. But they are almost always thought provoking, and often critical. The process of trying to work out the answer has value, imo, even if we don't reach a satisfactory conclusion.
