I was one of the earliest on FB. It's mostly an address book for me now. I'm sad sooooo many acquaintances and relatives are there, and yes, it would be a lot of effort to get their contact info or get them to use other messaging platform (but I've started doing that).

For 15+ years, I've thought long and hard countless times about what could sustainably replace social media platforms that do not serve us well. I know a paid app is not super likely to succeed, although WhatsApp did use to cost a dollar! It seems like a nonprofit wouldn't be that great, and so I wonder about a mission-driven public benefit corporation (not to be confused with a B corp, though it could be one of those too). Of course it has to be cool or no one would use it. Not a fuddy duddy wannabe social network. Anyway, to sustain itself, would ads or paid offerings (that don't harvest personal data) be successful?

Happy to discuss with anyone interested!
