One approach is to post an old, valuable thread (from Reddit or elsewhere) to HN, where annotated/appended conversation can continue indefinitely, especially if it reaches the HN front page for a one-time infusion of new readers and commenters.

What we need are search engines to offer an opt-in view or keyword which prioritizes this genre of valuable older evergrowing content. Perhaps Brave Goggles can be adapted to this purpose, using HN reposts and other signals of longevity.
