I haven't used Facebook in 10 years but my friends have shown me it. What's there to distribute? The chat functionality? The main feed is just a heavily curated stream of garbage that's vaguely influenced by your friend's list. It looks like there's nothing there other than this bizarre social pathology that's been continuously optimized and iterated to be as addictive as possible.

For chat you have XMPP, for feeds you have RSS and webpub (mastodon.) There's ical for sharing events of course.

Sure - we had it pre-internet with BBS's. There was even a standard for sharing message forums across them - FidoNET.

It may look crude from todays perspective, but there is zero reason the same concepts couldn't take root today. The big problem is friction. Just logging into to some "free" service that someone else runs for you is all most people want to think about.

I think there is a huge opportunity for a modern revival of concepts like BBS's and FidoNET, but with a modern spin on UI and communications. instead of the master nodelist like FidoNET had use a distributed directory along the lines of DNS. Heck why invent a new protocol - just adopt DNS with a few tweaks.

It doesnt need to be distributed,just needs oversight thats not commercially or politically biased
