Otherwise, why would X now support longer posts, right? 240 characters are not enough, apparently, for enough people.

I think the longer post are for people who can pay 8$ a month. Of course it's a microblogging platform, but paying to be able to write longer posts don't really make Twitter a traditional blogging platform.

In reality, the length of a post isn't much of a value, but on Hive, we tend to follow people or consume content that means value for us. So value is probably not universal, but 25 years is the definition of longevity.
