Moved this to tbp.staging.1dom.fun, because I know it (was) a semi working activitypub instance I can use for testing potentially not working instances. Originally used it for experimenting around https://github.com/tinyBlogPub and microblog.pub, but I've since discovered Fedify, which gives a far more contained activity pub implementation to work with. So I'll deploy a version of this site built with Fedify soon, and use this tbp instance for testing it (and stop spamming activitypub.academy so much.)
Remember, as per last subdomain shuffle, all posts before this one will have broken links etc. as old subdomain will still be in the DB, and new site uses different IDs.
...like this, I don't think I've got username/id/alias stuff quite correct yet: @1dom@staging.1dom.fun should work but is not correct...
