If they have a picture of a pile of books they have supposedly read as their banner, or have anything in the profile advertising themself as someone who reads', they're midwits. At best.
True erudition speaks for itself. The sage knows their next tweet or a cursory look at their profile, will provide sufficient indication of their sagacity.
It is the midwit lectiophile who equates reading with brilliance and based on that misapprehension, passes off the superficial as substantive to appear smart.
Look at me, I read a lot. THEREFORE I am clever
