How to use Mastodon without feeling lost

So the social media hellsc…sorry, landscape is a bit chaotic these days. Like many people, I decided to stop using Twitter as much as possible and have been exploring alternatives. One of the places that clicked with me was Mastodon. To be honest, I tried it a few years ago as well and didn’t really grasp it at the time, but this time I got it.

Now, many people in my circles are actually on Bluesky and I haven’t really been interested in that because it’s such a walled garden. I can’t see what’s happening there, so how would I know if I like it?
