The chronological order is quite subobtimal. You still want to discover new content/ideas/conversation. It's easy to miss out on a lot of what your followers have been tweeting if you don't check it 24/7. On the other hand, when you sit for an hour to check twitter, the following tab will dry-out immediately and you can't discover anything new unless you go to the For You tab which is basically a mix of stuff.
Indeed if you're active, and like stuff, the algo improves and shows you lots of relevant content. But mostly from the prominent accounts and only viral ones. So the point of the post stands.
My experience is different, perhaps because I follow people from both Europe and US (and some in Australia and Asia), so around the clock I always have 10-20 new tweets to go through, which is just as much of social noise that I have time for anyway... but it's still the most reliable source of information for my home country daily politics (because local media is censored heavily) and also gives me a good bird-view on what's going on with web-dev and AI industries (my primary professional interest). I have accounts on all alternative platforms, but none is giving me even nearly that good signal/noise ratio...
