—Concrete status symbol: The Facebook CEO’s start-up status symbol: a massive cement-floored HQ in Palo Alto. Zuckerberg told Bloomberg News he wants his staff to remember “we’re way closer to the beginning than the end. A lot of times buildings can be a signal that you’ve made it. I would rather that our building feel much more like a very large garage.” A large garage where you can get three free meals a day and play games.

—Funding: In May, Facebook took a $200 million investment from Russian PE firm Digital Sky Technologies, valuing the company at $10 billion. At the time, DST’s Alexander Tamas told paidContent: “The company does not need the money but I think it’s good for a company to have ‘optionality.’ You don’t want to be constrained by funding if you want to move quickly on something.” Zuckerberg told Bloomberg: “We think of that mostly as a buffer. ... We didn’t take that round of financing with any particular goal in mind.” Facebook acquired FriendFeed earlier this month but the price, reported to be nearly $50 million, was said to only include $15 million in cash
