Many HN articles could be summarized in a tweet

Anyway, isn’t a headline already a good summary? Tbh, 50%+ of my comments go into threads which I never tapped the link of, or at least I check comments first. Partly because a discussion is more interesting than an article and the latter can be seen simply as a pretext for chatting about something relevant (often not).

Edit: Also some users, either author or someone else, may write a summary as a comment and/or warn about lengthy post style. Seen it, done it.
