I guess it depends on how interested you are in what’s going on in the world, whether it’s relevant to you or not.

Even if I was just to look at the news that directly relevant to me, there’s plenty that (rightly) doesn’t make it to HN. For example, if there are an increasing number of terror attacks in a part of the world I’ve been to or plan to go to then I’d consider that news important but not HN-worthy.
