An introduction or FAQ as to what all those terms mean. What is a local timeline? What is a federated timeline? Why would I want those to be separate? Which one do I use when I just want to see toots from people I follow? And why is it that sometimes when I visit some person’s profile page, it says I don’t follow them even though I do?
As a long-time Twitter user, I find the lack of initial hand-holding utterly frustrating.
