It's mostly not. The vast majority of daily political yammering and scandals has no effect.
People mostly use politics as a way to dodge real problems in their life that they could be solving. You see this most clearly with the way people bat about words like "capitalism" into nonsense definitions. Their criticisms are almost always manifestations of personal issues.
More generally, people mature when they stop believing politics will solve their problems. It is very sad to see people who spend years hoping their candidate will get into office to reorder the world for them (spoiler, they won't), when they could change how they live today to actually reflect their own values.
As for breaking news, etc. If its actually important, it will get to you anyway, I promise.
You don't have to spend time on Twitter, but if you're looking for internet places to go like the OP is, you can find things there that you will never find elsewhere. I'm answering his question sincerely. You can make new friends and start new collab projects through places like Twitter and Hacker News. I've done it! You're not gonna get that reading CNN or BBC or whatever. You're probably not going to get any actionable, meaningful information from news sources like those, especially day to day.
Twitter is 100% amazing, hugely underrated, and a return to the mode of being that we had pre-1500's, where most knowledge was obtained through dialogue instead of one-way broadcasts, and I will die on that hill.
