@atomicpoet @stefan @fediversenews I love it and I will share it.
My only note would be that the icons could correspond with the fediverse parts similar to the non federated sites, for example the icon of Instagram could turn into Pixelfed, but the Pixelfed icon is somewhere else in the second diagram. One of these days I saw someone asking if there was an equivalent of Pinterest around here and that could help to solve those questions.
