That more or less reinforces his point, actually.
Whether you put Zuckerberg's success down mostly to luck or mostly to judgement he's one of a number of kids who find themselves in a position of having a corporate giant to manage with no prior track record whatsoever.
In that highly irregular situation hiring leaders who he'd be happy to be working under in the more regular scenario that he'd left Harvard to get a job seems an eminently sensible acknowledgement both of his limitations and of the kind of company he wants to build.
It's long baffled me that Facebook is as valuable as it is, but I'm consistently impressed by the anecdotal evidence of Zuckerberg's nerve under pressure and decisionmaking. Almost all of us would have sold out the moment someone offered $7bn (if not $2bn, or the numerous multi-million dollar offers that must have come privately before that). He reminds me a fair bit of Bill Gates in that I find a lot to admire in how he's got to where he is even though I'm dismayed that his product is taking over the world.
