Earlier quoted context omitted.
I was not complaining about the summary, of course.
HN threads are supposed to be conversations, and summary comments don't fit with that. Reciting a summary into the public record is a boring addition to conversation in its own right—imagine someone doing this in person—and makes the discussion more shallow, since it's no longer grounded in people having read the story. HN readers can, should, and do read articles, find out what's interesting about them for themselve…
This is the only part I take serious issue with. In casual conversation with people, they sum up stories in a couple of sentences all the time, and I thank them for it.
And not every conversation thread requires a complete understanding of the article. Most of the comments on this story are about a deficit of basic journalistic fact-checking in many news outlets. That doesn't require knowing anything about recycling programs.
I don't think that discussion is shallow or bad just because it's somewhat tangential. Some of the most detailed comments where I learn something new are somewhat tangential to the story they're posted on.
