For what it's worth your blog does show up fine in NodeBB as well. Perhaps you are missing the @context property and so Mastodon is refusing to parse it?

silverpill@mitra.social nice job! Congratulations on the release now you must maintain it for free forever.

rwg@aoir.social I'm not actually sure! You'll have to ask reiver@mastodon.social about that one. Let me know too!

@julian@community.nodebb.org Makes sense, thank you!

decentered@social.wedistribute.org it's been awhile! Looking forward to it.

jenniferplusplus@hachyderm.io I think it might be the Unicode escapes too. I don't think they're necessary.

@reiver@mastodon.social apologies if this is inappropriate to ask, but has there been any thought given to speaker fees? I'm enthusiastic about ActivityPub and love to speak about it, but I'm not in an secure enough place financially to fly myself to Vancouver without some sort of arrangement in place.

phillycodehound@indieweb.social agreed, you've got a sale from me! cc andypiper@macaw.social
