@linuxliaison@sir I did experiment with getting something that looked a lot like 6LoWPAN hacked on top of AX.25 but it was not very reliable even without the soundcard modem. I still believe it's a realistic option though and might revisit it one day.
At this point, this is mostly a testing instance. I'm curious about the moderation and administration features available to Mastodon. I want to use the knowledge to better communicate with admins in the future.
