I think that's what makes summaries so difficult for skimming news, like on HN.

For most professional use-cases, you kinda know what types of stuff you expect in a summary so you could possibly create templates. For example, internal calls are mostly around deliverables, due dates, blockers, etc. When casually reading, you don't know what you'll come across so getting a summary that really "hits" is difficult.
