Off-Topic: Most stories about politics, or crime, ...
If they'd cover it on TV news, it's probably off-topic.
Yes, this is important, yes, it's newsworthy. No, it's not "Hacker News". It's all over the news, and there's nothing specific about hacking, or start-ups. It's not even of "deep interest" in any real sense. It's tragedy, pure and simple, and then it becomes politics.This shooting is unprecedented in the US as far as the number of children killed, and will mark a point in history. Considering I don't even watch the news or go to any news web sites, if I hadn't heard about it on HN, I probably wouldn't have even known about it to be honest.
For a shooting, yes. But the 1995 Oklahoma bombing included 19 young children among the 168 killed, including all 17 children in a daycare in the building.
This level of death is, sadly, not unprecedented. And I guarantee you that in 20 years it will be even less remembered by the general public than Timothy McVeigh is.
