It sounds like you have a lot to teach us about query writing, but gratuitously putting someone else down, even when they don't know as much as you do, is not ok here. It violates both important rules of HN comments: civility (it truly is gratuitously negative) and substance, because it impedes the absorption of real information in your comment.

In the future, please edit that stuff out and stick to the substance when commenting here.
