One solution to this that I’ve been thinking about is to have a separate section of the page filled with rationalist art and fiction, which would prominently feature HPMOR, Unsong and some of the other best rationalist fiction out there. I can imagine that section of the page itself getting a lot of traffic, since fiction is a lot easier to get into than the usually more dry reading on LW and SSC, and if we set up a good funnel between that part of the site and the main discussion we might get a lot of benefits, without needing to feature HPMOR prominently on the frontpage.
I think this is a great solution.
