I have a few public shared articles and one of them I've changed a couple of times this month. It occurred to me that there's no mechanism for certain people who I've given the link to to know that the page has changed. Would be nice to be able to allow users to "subscribe to this page".
Otherwise they'd never know that it was updated.
Only downside I can see is if we use the "regenerate share link" button, I haven't done that but I assume it generates a new random link, so the subscribed users would have to follow whatever the link is changed to.
