After seeing the Gemini, Gophers, and Fingers post today https://news.ycombinator.com/item?id=48297467 I wonder if they would pair well with Reticulum

These ideas yes, but these networks already have a concept of message oriented semantics and so there's not much of a need to rebuild most of those protocols. A lot of what Finger, Gopher, et al does is define the application layer semantics to transmit documents over stream oriented protocols.
