Don't worry, I hear ya! I'm currently 4.9 hours in on my first run of the story game, Detroit. People in the reviews say it is a short game and they have less than 3 hours playtime ... but I don't wanna miss any narrative or clues! haha!
I joined Mastadon in December and that's when I first tried to understand it all. I researched a server to join and it was right confusing ... what if I picked the wrong one? Then I pretty much abandoned the account because I didn't understand how to stay on my own server while browsing around (also didn't help that I'd never used Twitter either, so I didn't actually know what I sposed to be doing lol).
Then the whole reddit debacle happened and I signed up for a Lemmy & Kbin. And there was all the jargon again. But I think because I was actually jumping ship from reddit, this time I wanted my move to have staying power. So it was unusual for me to "skip the tutorial" but I was getting so frustrated with the jargon, while I could see others were already having conversations. And it was through the participation that the jargon finally defined itself. I even use my mastodon now, as well!
