"Who on earth" doesn't only speak of quantity, it also speaks of quality.

The amount of decent, quality people with something to say and contribute to the Twitter is down to almost nothing, relative to what it was prior to elon.

You can lose "just" 20% of the cereal in your bowl of lucky charms... Yes, most of the mass is still technically in the bowl, but you can lose all the marshmallows in that equation, meaning you've lost all the color, texture and flavor that made the whole thing interesting in the first place - you're then only left with the mostly flavorless, empty, gray, soggy kibble pieces. You're mistaking a pulse, for a meaningful quality of life.

So, that's modern Twitter, it's the plain gray kibble* disintegrating in warming milk. And for "fun" they've actually added dog shit, rat poison and rusted razor blades to the kibble.
