The reason people keep using Twitter it's because it's designed / evolved to be very addictive. Most of us don't engage our rational mechanisms to go "I am about to spend X minutes engaged on Twitter, what's the cost/benefit?" We just do it, and later feel bad about it.

If you've been on Twitter since the early days, you have noticed how it has become more and more about dunking and hate-quoting. Once you have an algorithm that decides what content causes the most engagement, you learn that negative emotions make people act. It's hard to scroll Twitter and not want to yell at something you disagree with. The medium itself does not lead to constructive conversation. This comment would require a Twitter thread, which is a scary thing to write. Every single tweet in a thread can be taken out of context, and you have to write accordingly.

As a company, Twitter has stopped innovating a while ago. The product has been stagnant, and so has the market cap. I expect that eventually it will collapse when the most interesting people to follow simply stop engaging, but that might take years.

My solution is to engage as little as I am capable of. I deleted the app from my phone, and I have a personal rule of only posting inoffensive shower thoughts that almost never get any reactions. I never get involved in an argument there.
