It's not just you — no one is posting on social media anymore
(www.businessinsider.com)
This is a most excellent place for technology news and articles.
We've run a private chat server for friends 10+ years now with channels and that's where most sharing goes on, whatsapp chats with some, and I've basically moved to Discord for other interests and still use forums for some. Public social media is more for profile curation, displaying a highly curated identity.
