Something folk may not know about Mastodon is that some apps allow for you to add new accounts, so you can fluidly switch between them. 'Tusky' is an example of this. That way, you don't need to move to a new server, nor change anything to your existing Masto account, when you join one. Perhaps that helps those folk writing in saying they'd like to join https://collapsible.systems/about, but worry they might have to move entirely.
@neauoire Collapsible’s tardigrade rule reminds me of your black and white avatar rule. I swear I once read something smart about why to do that, but regret I can’t find it.
