Thanks! I have searched my browsing history somewhat thoroughly as well as links sent to friends. I can't rule out that it was on Medium but I'm certain I found it more than a couple of months ago (definitely a whole season ago)... Maybe it was reposted later?

Feel very silly having lost it because even when I read it I knew I'd want to read it again. I'll go back to scouring my history if no leads turn up here!
