I mean Facebook for example, at its core for an end user it really just mirrors what the Internet was built to do. I can easily host my own profile and allow people to log in to it and talk to me. How did it become so dangerously centralized?
(sadly, cheep.com is already taken or I'd be on that like white on rice...)
Network effects and there's nothing out there better than Facebook.
Freestanding sites lack this, and it turns out that behavioural costs matter.
