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.

Among his topics of interest are envronmental science, evolution, astronomy and space exploration, linguistics, and technology. 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.
