I read it to mean, the type of person who begins a comment with:

> If only matters of interest were limited to the things you could "absolutely fathom" how much simpler our lives would all be.

Immediately proceeds to label the parent comment as "snide" and then feigns misguided ignorance when met with exasperation.

I'm not xyzsparetimexyz though. Merely a person amused by the rapid devolution of communication from those trying to take the sanctimonious high ground on how sacred all forms of written speech should be, directed to machine or otherwise...
