       | Systems. Text-only protocols, heavily immune to the ad industry.
       | What a time to be alive!

       | I wonder if some of the nerdiest corners of the internet from
       | nowadays do not make the exciting 90s pale in comparison (all
       | this looks like aspects of a potential renaissance).

       | As hobbies, they all sound amazing. Even though, or perhaps due
       | to their apparent futility. "Secession from the broadcast" and
       | "the knowledge" come to mind. A possibility, among many others.

         | use those frequencies (13mhz), so doing it in dense, urban
         | enviroments is hard (unless you have roof access).

         | Otherwise, with lora and a lot shorter ranges, you can create
         | mesh communication networks easily, with $20-$30 of hardware
         | (already assembled) - eg. https://meshtastic.org/

       | simultaneously.
