I'm a poster on lemmygrad. That is the extent of my involvement in fediverse stuff. I am neither tech savvy nor interested in becoming so. What is Mastodon? Is it like the twitter what lemmy is to reddit? I'm not clued in in the slightest and not even sure if I should be? Do posts from Mastodon get moved here like other instances of things like lemmy do to lemmygrad? Do I now have to read the insufferable takes of twitter refugees over in mastodon?
