For example - I can create a list of lead-runners on Machine Learning and add the people I follow who are well-informed on the topic of Machine Learning to this list.
Then when I view my Twitter Feed - I can choose to instead look at a feed from a list. If I want to get "What's Going On" in Machine Learning, I visit that list and see a feed from these leaders of Machine Learning.
Do this for all of your interests and you can organize your feed to get a quick grasp of what's going on everywhere instead of being blasted by noise on your main feed.
