I'll take the other side of this. While there certainly are examples of click bait and inflammatory BS on Twitter, there is also an element of legitimate thought leadership that can go viral in a way you just don't have on any other social media platform.

There are few other platforms I can think of where someone with deep expertise on any subject can publish interesting, informed takes on their field- On a platform where the barrier to entry to publish is near-zero, provided with a random chance to go viral.

When I used Twitter, seeking out and following these kinds of experts actually made the experience of Twitter a rich and informative platform- albeit one where you constantly needed to "weed the garden".

The problem of course is that was a thin layer of wheat in a big bucket of chaff- but there is a better answer to "best alternative to twitter is no twitter": The best alternative to Twitter is one that can maximize virality for expert opinions; incentivizing other users to write engaging, structured opinions. Try to build a system where the best way to engagement farm is to show real thought leadership.
