What are you missing in the JoinFediverseWiki?

I’d like to grow the wiki.
For that purpose I created a Todo list:

https://joinfediverse.wiki/Join_the_Fediverse:Todos

I’d for example like to see a page about art in the Fediverse and a page about racism in the Fediverse.
Also there are a lot of “What is…” pages missing about many, many Fediverse projects.
What else are you missing?
