I said nothing at all about anyone being cretins; sounds like you are being a bit defensive. The post I was responding to said specifically that he used scores as "which comments to keep an eye on" and to avoid "getting lost in the text". But actually reading the text is the only way to absorb the information. The biggest problem I have is with following a comment back to its reference when there are a lot of intermediate comments - allowing comment levels to collapse, like emacs outline mode, would help.
