Is there something broken with uploading images to public gists? My images all end up bring private despite the gist being public ... which kinda breaks how I used to host images for my Github repos
I think you Lucifer don't know what I mean because you never worked with Github Gist.
Gist can be seen as some sort of special repo(actually it's a git repo) but optimized for sharing small pieces of code(usually a single file). A real repository would be an overkill for such a purpose and also it doesn't support comments the same way Gist does.
Think it of something like Mastodon but optimized for sharing small pieces of code in a single file or at most only a handful. People could comment, fav, boost, etc.
I believe ActivityPub can be used for such a purpose.
