Been thinking about this idea I've had for localized internet systems that run independently of internet connection and allow for organizing/sharing of info outside of surveillance:
I also realized that this system could just serve up txt files of literature, keeping it small. With the esp32 being so cheap, you're essentially designing an electronic "pamphlet handler", that can serve up union literature without identifying the users.
Cybrespace is an instance of Mastodon, a social network based on open web protocols and free, open-source software. It is decentralized like e-mail.
