Have been sitting on it for 8+ years. :)

My plan was to try to find the "answer" for videos in comments. Never really got around doing it, but LLMs make the possibilities more interesting and easier.

Edit: this is also a good opportunity to ship something like this: https://hn.youtldr.com, like Karpathy's HackerTube, but with the new videos from "HN-vetted" channels.
