Don’t forget, you can follow hashtags too! So if you want to see toots (posts) regarding a topic that interests you, just follow a hashtag like #ukrainewar, or #linux for example. That’s also a good way to to find people to follow.

I honestly have no idea how Twitter works so will just have to take your word for it lol. Loving Mastodon though, I've had two accounts since November, both on small niche instances and both have nice active feeds and as much conversation as I want :)
