Nah, there's a lot of nuggets there. Keep away from the political trash and follow people who post interesting things that you like. For example, I like old video games, so I follow people who talk about old video games.

There's lots of nuggets. It's not even hard to find them among all the shit. If you're following someone whose content you don't like, just stop following them. One big tip I wish was more obvious is that you can turn off retweets from specific people you follow. So if someone posts cool content themselves, but also retweets a bunch of political trash, you can get the former without any of the latter.
