It's an inherently toxic format. It promotes incoherent, contradiction-ridden, emotionally-driven, short-attention-span meme-think.
IMHO Bluesky is no better, which is why I'm not there. It's the same format, an incoherent soup of sound bites competing to emotionally trigger you into amplifying them. This format is the kind of thing a mad scientist would design with the explicit goal of rotting the human mind.
The good thing about books and longer-form works... even things as long as Reddit and HN comments... is that they can encapsulate complete thoughts that are connected to other thoughts. Building systems of thinking is how humans reason coherently about the world. Meme soup reduces us to some kind of animal level of grunts and short-horizon reactions but with language. It's gross.
I've been calling "social" media companies in general "the tobacco companies of the mind" for years.
However, there is much wisdom in McLuhan's "we become what we behold" -- and consuming too much "social media" turns one into a performative puppet. Twitter is the distilled version of this (Jaron Lanier called it "Twitter Poisoning").
If Elon Husk huffing Twitter 24/7 while owning Twitter isn't a case of "getting high on your own supply", then I don't know what is.
Are infomercials toxic? maybe? Is banning them useful? maybe - can you find them addictive, as a post-TV individual? I can't, and I can't get schezophrenic like those perpetually enraged Twitter users, either.
I think it's just that those people, including Musk, didn't have the new form or literacy, a stronger grounding to the reality, required to be online. Twitter/Bluesky architecture itself, IMO, is about 10^2-5 less toxic than anything before it.
