Articles on Quill don’t seem to have the ability to syndicate to twitter and mastodo, so I might end up using micropublish. Bit frustrating to figure this all out, but also kind of fun to be honest.

If you use the Syndication Links plugin and configure it, Quill should be able to find your Twitter and Mastodon “endpoints” on your site and provide you with buttons to syndicate to them.

It looks like your theme has an extra u-photo on it that’s causing that avatar image to be sent to Twitter by the way. The way the microformats are set up is also causing them (Syndication Links) to display too, but it’s fixable with some tinkering. You might try IndieWeb chat to see if someone can help you troubleshoot it.
