The Criticritic is Sterling Jones, an IT security design engineer who works in the telecommunications industry. He started using the Internet in 1984. He has a background in criticism from studies at NYU. He blogs about topics that he thinks are important.
The Criticritic used to blog about critics. As the publishers of reviews face mounting challenges to monetizing text, the quality is diminishing quickly. This in turn makes the work of criticizing critics far too easy. So, he doesn't do that as much any more.
Naturally, when filling out "About the author" sections, he refers to himself in the third person. If you know the Criticritic personally, and you thought it was odd to read him referring to himself in the third person, but you've never thought the same thing about other "About the author" sections written by people you didn't know personally, then the Criticritic pities you.
