Despite there being pretty good alternatives to Reddit (think Lemmy etc), Reddit still can’t be matched for the sheer volume, breadth, and depth of content to be found. Having hands-on moderators also means that the Subreddit rules are pretty well adhered to.
What you end up getting is strongly topic focussed content, which also gets rigorously crowd vetted by the community in each Subreddit. You can find news along with some balanced commentary and moderation.
But Reddit is more than just the big general r/news and r/worldnews that many know about. There are also Subreddits specifically focussing on Uplifting News, Science, Good News, and more.
So, if you’re looking for more positive news (wanting to actively avoid bad news), some of these Subreddits maybe worth looking into.
The linked article also goes on to explain how you can create your own custom feed.
If bad news gets you down, it is well worth spending some time to focus on places where you can get more positive news for a change. Too many news outlets (and even social media posts) want to use clickbait headlines and content focussed on angering, upsetting, or alarming viewers into reading their content.
