A very long read, but a very engaging one at that.

After Zuckerberg launched Facebook, he continued to seek Greenspan’s advice. While most of their exchanges were about the nuts and bolts of the site operation, Zuckerberg occasionally revealed ambitions that were far beyond the scale of his classmates’. His new social network, he wrote, would do more than “get people signed up” and “get people psyched.” His goal was to create something new, something that touched a deeper need. “I kind of want to be the new MTV,” he declared.

But Zuckerberg had no interest in giving Greenspan any credit for creating Facebook, let alone a piece of the action. In December of 2004, when Greenspan decided to “admit defeat” and ask Zuckerberg for a job at the rapidly expanding company, all those months of advice proved worthless. “We’re looking for someone with more engineering experience — like, 10 to 15 years,” Zuckerberg told him. The guy who first created an online facebook for Harvard couldn’t even get a job at Facebook.
