Just bring back the 'Activity' or 'Discover' feed. They were perfect additions to spend more time on Twitter (and discover new things). And that's what this is about, right?
I recently wrote this: " I worry that a lot of (young) people seem to hit every follow button they come across, after which their Twitter timeline becomes an uncontrollable mess (bots with 100’s of tweets/day) to which they never return. Too much hassle. I’m very selective who to follow and to keep a readable timeline. Again: this is me. But it is part of a larger problem on Twitter to create a better experience where the better content sticks out more. Snapchat specifically and probably incidentally deals with this problem. Stuff is just gone after a certain period."
