I was right there with you for the longest time, until I realized it's all about very carefully curating your feed. Only follow thoughtful, interesting people who's opinions you respect, and purge the nonsense with extreme prejudice. It's probably the best way of staying on top of what's happening in any particular industry/field of study if you look at it that way.
I tried doing this and just wound up with a bunch of garbage content from interesting people who's opinions I respect at a rate of hundreds of garbage posts per day.
Then I uninstalled. I just don't get it. Maybe I just like crap people or something.
