I would like to invite you to read this article: https://en.andros.dev/blog/ba142044/twtxt-vs-org-social-the-... What do you think?

Interesting! My biggest reaction is I don't use Emacs. Is Emacs a requirement? You're right that Org adds features but it also shrinks the pool of people who will try this.

It's not necessary. I almost always use iOS.

I think twtxt is really cool. I have one on my site but I don't use it, unfortunately
