#ZeroNet pros:
+ easy to install (on Windows at least back then)
+ could browse "clearnet" (regular web) & Zeronet at same time (unlike I2P)
+ any kind of site possible (blog, social network, forum, wiki, chat room etc)
+ your Zeronet ID worked everywhere, didn't have to sign up to each site/service
+ like a site? just click "clone" button & you can have your own version of it!
+ easy to block people, including subscribe to block lists maintained by others
Oh, & the pros of #Zeronet #P2P vs #decentralization / #Fediverse
+ no need to pick an instance (& the research / issues that entails)
+ no worry that the instance you pick will disappear / turn heel etc
+ no need to ever migrate instances (& the complications that entails)
EDIT
+ no need for self-hosting expertise, reverse proxy, Docker containers etc
