On the other hand I do think LW didn't really learn what I hoped it would from my old comments, so maybe this is more a problem of me sounding like a broken record because I have to keep repeating the same points, since this bores me I do it more poorly than before. So perhaps I need a new venue.

My suggestion to you is the same as the one I gave to wedrifid: write more posts relative to comments. Comments are for asking/answering questions, or fixing mistakes in other people's posts, or debates. If you think you have something to teach LW, please do it via posts, where you can organize your thoughts, put in the effort necessary to bridge the inferential gaps, and get the attention you deserve.

(If the suggestion doesn't make sense to you, I'd be interested to know why. As I said, I made the same suggestion to wedrifid before, but he didn't respond to agree or disagree, nor did he subsequently write more posts, which leaves me wondering why some LWers choose to write so few posts relative to comments.)
