But the pics sometimes included with Leviathan handle do not look like KJ, who I met working the front desk at JR. Also, he is pretty affable in person when engaging in small talk.
Furthermore, there is extra rhetoric and emotion in KJ's writing style (like someone who has rigorously studied good English lit in his youth and still enjoys the art of creative writing, but applied to the present context).
I would say the underlying thought process in the Leviathan handle is somewhat more analytical & business-like (like an ex-corporate consumer product manager).
So, your hypothesis that they are one and the same doesn't add up 100% (but I have not been around the scene for years like you).
