Yeah I feel like this would be better as summaries of textbook chapters or information rich sources, a lot of HN posts are already basically text summaries of a complex topic that it doesn't really make sense to further summarize them.

To me, the use case is to go from an often opaque headline ("Using Nix and containerd with Jev on macOS") to a paragraph which hopefully gives some strong hints as to what those things are and why it's interesting, because the articles often are written for an audience already deeply into all the topics. Because often a few of those terms I might have no clue about and thus scroll on by, but with a brief "why you should care" explanation, I might realize it's actually something cool.
