@Sheril @ShaunTheAuthor Welcome aboard and have fun. I tend to view Mastodon as a coffee shop where a lot of little convos are going on and you can just join in or do some people watching. Sometimes I check out other instances with the Federated section and just stop the feed and go down a bit and see what's going on and comment.
I like that it's not just some America-centric thing and you get a lot of perspectives from around the world (and it makes me wanna learn German since I signed up under a German-run instance--hee hee). Because it's not full or our screaming American politics and echo-chambers, it's a lot less stressful to just navigate and say stuff. Sometimes I find off the wall stuff to comment on and people are surprised I replied.
You won't always be engaged with, but there's also not that stupid pressure to constantly engage, either, which is fair. Even though it's online, my own introvert battery can't handle constant scrolling and posting... and yet this morning I'm making a liar out of myself by making some rather lengthy responses (hee hee). In short, have fun.
