Oh my god, completely! I use Instagram (mainly for marketing), and I'm astounded how many people I'm seeing just hopping along on the bandwagon, like it's something innocent and cute and stylish. It's scary to think how desperate people are to belong, in a way. To signal they're one of the herd.
I saw an article about this Threads business on Medium, and they actually used the phrase "don't get left behind". Exactly. FOMO seems to be powering this mass, brainless adoption. And not good FOMO, either.
Oh yeah I've noticed how the marketing is very 'dont miss out'!!! It feels like a fist fight between Musk and Zuckerberg too, like they are flexing, and we're all in the ring. Just wrong.
