Are you frustrated because you want to see substantive and interesting posts in the discussion section, and not just meta issues? I think you have some common ground with ialdabaoth that you may be missing.

Here we have a valued and contributing member of the community who is frustrated with their recent experience and is reaching out to the rest of us for help. Your response sounds like a your-problem-is-not-a-problem solution. Couldn't someone make the same kind of reply to you? (e.g. "If you don't like meta-posts, just skip them. This one was even clearly labeled as meta!")

Currently, as far as I'm aware, LessWrong doesn't have any place other than Discussion to discuss meta issues. Perhaps one is needed?
