I just updated my ‘📢 Publish Quote’ shortcut to version 2.0:

Now you copy the quote before sharing its URL, meaning the shortcut is far more flexible and can be run from anywhere (like RSS reader apps!), not just Safari

This is a massive update with a bunch of new niceties, like options to include author attribution, saving copies of each post to Drafts, and much more.

Get it from the HeyDingus Shortcuts Library.
