This is an anonymous commenter to your article, Steve. I am not a Medium member and don’t have an account, so I hacked and am using Harper’s account so I could remain anonymous. If you must, ask him if these are really his comments and he will deny, deny, deny. If you’re still not convinced, you could also try language analysis, and you’ll see this sounds nothing like him (actually, he’s much more clever). Anyway, great job on uncovering the letter from agronomous!
