Mark Frauenfelder is the editor-in-chief of MAKE magazine.
He is a communist, whose magazine teaches people how to make their own things instead of buying them from the corporations that keep our economy running in top shape.
He appeared as Stephen's guest on the March 6, 2007 edition of The Colbert Report. During his appearance, Stephen challenged Mark to a marshmallow gun duel.
