I've struggled a bit with this decisions since I've made a fair number of real friends through twitter (people I keep up with in real life after) and come across a lot of interesting books, papers etc.
But I've come to realize that despite its benefits, twitter is ultimately toxic to your mind. I've seen far too many people I care about slowly dissolve into a fever of dopamine fixes as they slowly contort their personality into a stream of memes and rants looking to gain followers.
I always tried to fight the urge to post stupid shit just to grow followers, but anything genuinely nuanced or thoughtful you post will have virtually zero engagement. This is fine in isolation, but it leads all conversations to eventually degrade in to a miasma of garbage thinking that is just a mix of groupthink, rage and memes.
The final straw for me was finding myself angry about the vague opinions of people I don't really care about at all. This same type of thinking is what got me to drop facebook entirely years ago.
