I'm certainly all for reacting to your own post to stir engagement. Unfortunately I don't get a whole lot of engagement when I announce my post on social media.

That said, on Medium, one can gauge how much someone is into your post based on the number of claps they offer. I know that was the general idea they went for when they introduced that feature years ago. Though these days with more new faces on the platform, I'd say getting some reactions buttons could be something to consider. Certainly would help authors in figuring out what their audience thinks about an article.
