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.
I'm pretty big into the mechanical watch community. Insta used to be popular in that community, but the best content and discussion has long since moved off "social media" and into various private Slack and WhatsApp groups.
I've heard of a similar movement in other hobbyist/enthusiast communities.
For people I actually know IRL, it's virtually all WhatsApp.
Too bad whatapp spies on you just as much. For whole communities to be in private chats seems rather counter productive for new people to find it.
Agreed on spying, though I don't think it's any worse than posting on public sites.
The new people concern cuts both ways. Yes, it's moderately harder for brand new folks to learn about them and gain access. But it's far from impossible, and the additional hurdle or effort tends to substantially cut down on trolls, spammers, etc.
