I would argue trying to find news on social media is the big mistake. It's absolutely bad on Lemmy, but it's not that much better on other platforms. Any story that isn't a "win" for the larger portion of people on the platform will naturally struggle to get attention.
There's a whole rabbit hole to go down in trying to find a way to get a solid, rounded and accurate view of current events, but imo step one should be to throw away social media as a news source. It's only popular because the algorithms on other platforms will tell people what they want to hear.
