There are more ways to get news than reading reddit tho. I still get exposure to the "big" events through HN or simply by talking to my coworkers, and those conversations tend to be a lot more meaningful and nuanced than what I'd normally get on reddit.
Not getting every single detail of a story as it develops isn't really a big deal to me and, I'd also argue that following these news on reddit won't really make you more informed (I already shared one example where the news was discussed but the conversation was entirely off from the reality). Reddit only makes you feel more informed, but that doesn't mean that you actually are.
Well, remaining uninformed is certainly one way to prevent hysteria.
