@creatrixtiara ooh, so cool!
One thing, probably too complicated for the article, and not sure if not implied anyway, but: potential toot readership always includes non-Mastodon people. Public toots also appear on the instance about page (in the newest version), and on profiles. Unlisted toots appear on profiles. Both can be seen via instance preview tools etc. And all toots can federate to GNU Social instances that don't keep Mastodon's privacy settings.
@maunzikation oh good point about privacy! Thank you!
