Marc Andreessen invented the friggin' Netscape browser. Have you heard of it? He also wants you to know that he's the idea guy who shifted your computing paradigm by getting Netscape to develop webtop software. So while gabbing at the Churchill Club, Andreessen slyly noted the realization of his ideas. By Google. Today's featured commenter, WilliamMarkFelt, explains the thing about ideas:

I have been a great admirer of Andreesen since the mid '90s. He is no doubt one of the fathers of the modern internet. But really, he should can it about people using "his" ideas. He of all people should know that the internet abounds with ideas. Everyone has an idea.

Ideas are overrated and rarely original. The know-how to implement ideas, and to know which ones are good, that's where the real genius comes in.
