Why not avoid the algorithmic feed from Twitter and only look at what your chosen followed users are posting? Relying on a third party to provide both breadth of information and inoffensive posts is asking too much.

Just as in real life, not every person you cross paths with is worth your time. Wading into public spaces like Twitter requires some work on the users part to find gems of useful information … relying on the platform to do it for you is likely to never work perfectly.
