I hope the situation where setting up a fediverse instance on a domain "burns" that domain forever gets rectified at some point. I would really like to just use my nyquil.org hostname, but still be able to change platforms at some point. For now I used gts.nyquil.org, assuming that I'm probably going to eventually want to play with bonfire or iceshrimp.NET or some other platform, and can have them all running on their own subdomains until a time when I want to migrate to one of them.
