Thanks. Firefish is mentioned on the web page :)
There are many services not in the graphic. What do you consider to be good criteria for deciding whether or not a service should be in the visual?
When I designed it, the most important goal was providing an understanding of the diversity of the Fediverse and encouraging further exploration. Mapping the whole Fediverse is a challenge, and I believe would make the graphic more overwhelming, rather than sparking curiosity.
