I want to take a crash course in Fediverse. I was browsing stuff on Mastadon and voila! I found these communities on Mastadon but I wasn’t able to post anything, but I was however able to reply to stuff. I don’t know how this works. I won’t be reading it now, but I want to know more about Fediverse, so a book or documentary, something really detailed would help (just don’t send me a website please :')
If you are trying to interact with Lemmy communities, you’d be better off using a Lemmy account instead of Mastodon.
Up to some degree Mastodon and Lemmy can interact between them, but that will certainly makes things a lot harder for you.
It’s easy to find very oversimplified information or excessively complex info. Pretty hard to learn without someone that knows a lot answering specific questions after you learn the basics. Hopefully someone gives a nice clear mid level explanation for ya.
If you’re up for reading Internet standards documents, start here with the official standard for ActivityPub, the protocol that it’s all built on.
Here is an in-depth technical explaination video.
