I signed up for mastodon when he bought Twitter. The challenge is that I never actually used Twitter so I am lost on what to do with Mastadon. I repost and star posts that are fun but can’t figure out how to follow the conversation. Happy with Lemmy since it’s much easier to follow each conversation. Maybe I’m using Microblogging wrong.
My advice is follow hashtags for topics you like or are interested in. They will then show up in your feed. It's wonderfully personalized and I've found lots of great people that way with similar interests
I usually post my thoughts about stuff I consume (books tv series anime games movies music) or about stuff that gives me food for thought or opinions about what's happening in the world. Links to my music when I produce it too.
A few weeks ago I found that the server software of Lemmy wasn't really prepared for that yet. You were able to open a Mastodon users profile (it wasnt easy, though), but you werent able to subscribe to it as on Lemmy you cannot subscribe to users, and since content is only synced to Lemmy (e.g. from a community) if users are subscribed to it on your server, posts of Mastodon users didnt get synced, and so you didnt see anything.
I don't know if it has changed yet, did not try it again since then, but I think theres an issue on Lemmy's github repo about this
