hi new mastodon users, welcome to Vivian's Tips For Using Mastodon For People Who Know Nothing About It:
for a standard social media experience, do the following things:
- in settings (gear button) set your post privacy to "unlisted" by default
- don't check local/global timelines unless you really want to
that's it. IMO the public timelines are confusing for new users and will just get in the way. Oh, but also, use content warning (cw button) whenever appropriate.
