Author, Secret Diary of Steve Jobs
Why he matters: How could an anonymous satirist possibly matter enough to make this list? Simple. Not only is Fake Steve's site one of the most closely read blogs in Silicon Valley, but FSJ has great sources and (apparently) a pretty good line on how RSJ feels about the world around him.
FSJ is not so much Jobs's alter ego as his id, free-associating about everything from "frigtards" like Eric "Squirrel Boy" Schmidt to the "MicroTards" in Redmond. Peace, FSJ. Namaste.
