Maybe I suffer from too much skepticism, but this social media headline from Ad Age certainly grabbed my attention: "Facebook Finds Profitability Despite Nascent Advertising Model." Drilling a little deeper this morning, I discovered that this information came straight from Mark Zuckerberg at the Facebook blog, who, in the second-to-last paragraph of a post yesterday, said, in a "BTW" kinda fashion: "Earlier this year, we said we expected to be cash flow positive sometime in 2010, and I'm pleased to share that we achieved this milestone last quarter."
