Things I have learned from this and past articles (only slightly exaggerated): 1. Greenspan is unlucky and unhappy. If you have even a remote chance of success, make sure you never even have a conversation with him. If you do, you might suffer his wrath (including possible lawsuits, and your conversations being made public). 2. Losing the opportunity to be part of Facebook is the greatest loss anyone can have. Everything else is trivial in comparison. 3. If he did get the opportunity to co-found Facebook, he would have provided no value anyway: "maintaining even a weak friendship with me would have cost Mark a few billion dollars in future paper earnings"
