Negative.
He is a blogger in the blog section of the Blaze.
Just like Wordpress or Blogger.
Basically less than nobody.
It is an impossible concept. One cannot be less than nobody; negative units of physical being do not exist.
Well, unless you are saying that he is composed entirely of antimatter. Perhaps that is the closest to a negative unit of physical matter than can exist. It does bring up, however, the possible problems of antimatter-rendering of a complex matter-based physical life forms.
Can we be assured that an antimatter life form would operate in the exact same manner as a matter-based life form? Would molecular covelant and ionic bonds act the same in both anti- and positive-matter? Could nerves, digestion, and other biological processes operate the same in both a negative- and positive-matter universe? Or would they be so drastically altered that the very foundations of life would be unrecognizable between the two forms?
I'm afraid your concept, that this person is 'less than nobody', is so fraught with uncertainty and physical impossibility, that I suggest you will need to adopt another term.
Yours,
I checked the author’s “about” page. He’s the Editor of Blaze Books and an adviser to something or another. It’s not some random blog. If he says “our,” he must be referring to The Blaze.
