Politics aside, Twitter/X has become a bad place to share information on and to link to. It's a bad option from a technical point of view.

We can't read a multi-part tweet (or follow-ups from the author) or check the latest updates from an official account without an account, which requires a mobile phone number and sometimes extra verifications. A digital "town square" can't require an account and a phone number to read what's said there.

Same with Instagram, Facebook, Threads, Linkdin, etc.

I wish I understood why the majority of the AI discussions happen on Twitter/X.

Network effect. Most people worth discussing with are already there, so more people join the discussion there, and so on.

but it's a really shallow form of discussion, as most tweets are the equivalent of short-form videos of tiktoks.

Tells me how valuable they actually are.

Because obviously everyone who participates in a discussion has an account, so they don't feel this annoyance other than maybe when sharing a link to someone else.

Read Social and Economic Networks by Michael O Jackson.

A lot of crypto bro grifter crossover in AI.

why not?

Don't be obtuse. the reasons why not were spelled out in the GP.

[flagged]

Inertia. Twitter has basically no value, it's just a bad app and bad website. It was never actually "good" for information communication, but it was tolerable.

When it comes down to 99% of these "why are people using sucky thing?" questions, the answer is inertia. Never confuse popularity for quality, they're completely orthogonal.
