I’m going to go against the grain here and recommend that you NOT use Mint. I’ve been using a linux for a month now, so I’m new to it like you.
My first time trying Linux was Mint, and I didn’t like it at all. There was too much crap downloaded on it, and it abstracted the underlying systems too much, so I found it all very confusing. I suggest that you download a distro that Mint is based on, and then install the actual stuff you want on it.
Mint is based on Ubuntu, which is based on Debian. I decided to go with Debian as a total noob and it makes waaay more sense to me this time around. I enjoy customizing it to my liking rather than Mint doing it all for me—often in ways I don’t like.
I’m on lemm.ee! It seems to have a good balance of users and sensible defederation. On mobile, the app you use make a world of a difference too. Both Jerboa and Thunder (Android) were mid tier experiences, but now I’m using Boost and it’s phenomenal!
