I can’t tell for BlueSky because I have not joined yet, but I did create a Mastodon account months ago and I’m not sure what to do with it or how to interact with others. I find it confusing.
On Twitter I was mostly following a bunch of like minded people, liking their stuff, and I could see what they liked too. But on Mastodon there’s uuh, boosts and favorites?! I’m not sure of how it works or what I’m doing. I can’t just “like” posts? I have to boost them?! I found the people I liked that were on Twitter, but on Mastodon I feel like there’s nothing I can do aside from seeing posts and it’s just not attractive.
I like tech, old and new, so:

I"d also suggest Jeff Geerling but he’s close to a million subscribers.
