Twitter has nothing to redeem it. Even in communities where there’s attempts at substantive conversation the medium makes a horrible mess to follow.
Say what you will about Twitter, but at least the insults there are direct and tend to stay exclusive to Twitter - as opposed to neighbors convincing each other of the worst or your ability to land a job being sabotaged because your profile doesn't have enough keywords.
On Twitter these same people are much more likely to post a hot take than pictures of their kids or pets. The platform draws out toxicity even in otherwise easygoing people.
Most of my family and friends stopped using Facebook around 2015, and Instagram is predominantly for young people, vain people, or photographers.
