Scott C Gruber is many things: a web producer by trade, as well as a huge science and technology nerd, an aspiring speculative fiction writer, a husband and father, and a proud skeptic.

Appalled by the volume of magical thinking, conspiracy theorism, and overall poor logic in much online writing, Scott prefers to tackle his subject matter with a skeptical eye and a fact-based approach.
