Calc's cool Fedi instance list
These are some Fediverse instances I think are cool, especially for people new to the Fediverse.
I'd recommend Misskey for most people who want to get into the Fediverse. It's a customizable, comfy, and overall awesome microblogging (“tweeting”) experience.
Mastodon is a bit more easy for those coming from Twitter to grasp, and while being popular, lacks a lot of features other microblogging platforms have.
Unlike the rest of these, Pixelfed instead takes a more Instagram-like approach, and is what I'd recommend for artists and photographers.
Very customizable microblogging, but I wouldn't recommend it to new people as it can be harder to use and understand.
It's like YouTube, but can interact with all these different platforms.

I'd recommend my instance the most! (Totally not biased)
