@timorl I very rarely use "Dr" as a title. In fact the use of it here started as a joke but people came to identify me with it so I kept it, specifically given the STEM nature of QOTO it made sense. My personal policy has always been to keep my degrees private in most situations.
@freemo
I assumed it was mostly a joke, but the options you presented don't seem extremely serious either, so it seemed to fit.
