This is a good idea. I joined Mastadon with the influx last November, got confused and didn't return until the current Reddit debacle. I'm trying harder now to understand, but what would have helped was 1) a simple guide to getting logged in and 2) finding content and 3) being able to view it and reply (including understanding if I was supposed to use hashtags, etc.). Get someone started with a short list of popular communities/magazines, THEN show them how to branch out. #trainingwheels
