I used #ZeroNet #P2P ~2019, & it was great from the point of view of enabling users to do pretty much anything (social media, blogging, forums, chat, filesharing etc) without need for self-hosting or special tech skills. Just install & run, & you can do it all in your browser. A site you like? Click "Clone" & instantly have your own version of it!
(But there were so few people & so little content on it, & lead developer has since ghosted.)
We need something like that.
