For some reason, it seems impossible it build a long-lasting blog host. He didn't use Wordpress, Blogger (I'd ignore these, too), or Medium for this. My guess is that the network effects of social media are so strong that it's better to post a poorly formatted essay to a platform meant for shorter comments than to post it (and link) to a site that no one visits as a destination.
For sure the platform (Twitter) is why this has become such a common thing now. And why (commenters have schooled me), there are services trying to solve the problem https://threadreaderapp.com.
But (tangent), as far as building a long lasting blog host? I'm starting to believe that JAMstack (https://jamstack.org) is the solution. I think maintaining a full blown web server, for something that can be solved with a simple static website, is overkill. I'm working on implementing my own personal site in this fashion as we speak.
But getting the discipline and focus to write some actual blog posts is another story. So I guess I can actually understand the Twitter rants, even though I hate reading them :)
