Earlier quoted context omitted.
And if I wanted to message you personally with questions about it for an indefinite period of some weeks or months while I get oriented, are you okay with that? "Here, Doreen, here's my email address and my phone number. Don't hesitate to contact me. Happy to explain like you are my clueless little sister until you feel comfortable."
If you can figure out Twitter, you can definitely figure out Mastodon. They have similar levels of complexity — you're just not familiar with Mastodon's quirks yet. If you don't want to put in the effort, though, that's fine.
I think you are thinking of Mastodon primarily as a technical platform. I am thinking of it primarily as a social environment.
When I was active on Metafilter, there was a new social platform all the members were talking about. It was invitation only. I was homeless at the time and I was generally treated pretty badly by most members there. Nonetheless, someone gave me an invitation and I joined. And it was pointless because what few people I did recognize were people with a track record of treating me terribly.
If people have little walled gardens, but are hesitant for any reason to admit me to their inner circle, then there's no there there for me.
Sure, I can figure out the technical details, if I have reason to. But I don't have sufficient connection to have reason to. Walled gardens serve an inner circle of people. I don't belong to any inner circle that are using Mastodon.
Perhaps that will change. But it won't likely change by joining Mastodon. It might change by somehow becoming an insider somewhere with a group that already uses and prefers the platform.
