This is very cool! I too have been very curious about ATProto after reading Dan Abramov's blog posts on it: https://overreacted.io/a-social-filesystem/

One question, I tried sharing your site with a friend and the share URL is coming up as http://localhost/ which is strange and I've never seen before. Is this something that's possible to customise via meta tag, or is this a bug in my browser (Vanadium 147 on GrapheneOS)?

Seems like accidentally they uploaded a local development build of the HTML:

<meta property="og:url" content="http://localhost/"/>

<link rel="canonical" href="http://localhost/">

Yeah thought it might be something like that, I just couldn't recall off the top of my head which one would get passed to the share context.

This should be fixed now!

Definitely something on my end. Thanks for the heads up! I’ll try to fix it tonight.
