@marathon0 Interesting, some errors in this png:

Hubzilla is also a blog based on wordpress (that are spread on the fediverse)
Networking should have be wrote (micro-)blogging instead
Lemmy is a specific case as an alternative to Reddit.
Dokieli and Olkiare missing here, they are for scholar publication/review.
Beside Matrix ejabberd (jabber/XMPP) has also fediverse bridge
Gancio is a calendar for events

Is there someone that would create a itch.io like Fediverse tool, now there are lot of gamedev ? Itch.io is more and more restrictive on log in and only allow Youtube video.
