Note to fellow HN readers: while this is a good post, the article is NOT WORTH READING. Just note that PG appears on Businessweek and move on. Do not read his profile or that of other people unless you want your brain to hurt.
I can't back this up, but I'm doing this out of good will. I want to spare other HN readers. At the end of the day, the bottom line is: Because it sucks.
From the OP: "Since Mark Zuckerberg co-founded Facebook in his dorm room at Harvard University, the social networking giant has been dominated by a freewheeling culture of young, mostly male computer engineers. That all changed in April when the company hired former Google executive Sandberg to become Facebook's chief operating officer. Sandberg, 38, was brought in to provide some adult supervision and help Silicon Valley's hottest startup to grow up—and make oodles of money."
Not cool, BusinessWeek. I hope you get a[nother] hundred hours of downtime for dissing hackers like this. I hope you try turnaround after turnaround as new market entrants eat your lunch.
