Cranky Geeks is a technology-related Internet show produced by Ziff Davis Media centered on discussion of technology topics of the week. It is hosted by industry pundit John C. Dvorak. Editor of GigaOM Sebastian Rupley is introduced as "co-crank", and serves as both a weekly panelist and editor selecting the week's topics. Each week two guest panelists, usually selected from a pool of technology journalists and entrepreneurs, join Dvorak and Rupley.
