I think that you're taking the emotional tone of my message differently than I intended it because I use the word "unfair" differently from how many people do. To me, it just means "Something not shared by many people; a trait that may gain you certain privileges that not everyone possesses." It's a valueless judgment, because I've already come to terms with business (and the world) being unfair. I could use the word "unique" instead, but chose "unfair" both because unfair connotes privileges (which we are certainly talking about here) and because Peter Thiel has talked in the same terms about what makes business go round.
I certainly don't harbor any sour grapes toward Zuckerburg - that is the nature of business, he was prepared & prescient enough to capitalize on his opportunity and I was not. And it's not like life has turned out badly for me in the meantime anyway. :-)
