I'm Zack and I just found this mastodon hub. It's a fantastic constraint and I had to try it out!
I'm a fan of programming, rock climbing, alcohol, and D&D (I'm a DM for two groups right now).
Mastodon is a "FOSS" social sharing hub. A multi-host substitution for capitalistic platforms, it avoids risking a particular company monopolizing your communication. Pick a host that you trust — you can still talk with all hosts running Mastadon. Any individual can run a Mastodon instantiation and join in this social hub in a jiffy.
