Thanks @BeAware for tagging me!
@Artanux Have a look at https://jointhefediverse.net, it's also available in French!
You might also find https://fediverseexplorations.org interesting.
And perhaps some of my tools over at https://stefanbohacek.com/tag/fediverse/, such as https://data.stefanbohacek.dev/projects/fediverse
Hope you'll find something useful!
