Facebook (NASDAQ:FB) held its 2014 Q3 earnings call on Tuesday and although the social media giant's numbers were impressive, Wall Street was not exactly thrilled. Facebook's growth slowed from 3.125 percent last quarter to 2.27 percent this quarter. In after-hours trading, Facebook's stock was down 9.76 percent. Additionally, Facebook broke out the financials of its $22 billion WhatsApp acquisition for the first time, and they were a little disappointing. WhatsApp brought in just $15 million in revenue in the first half of 2014 despite having 600 million users. Ouch! And, what about the teen metric? Mum was the word, the world's social connector refused to break out any data about usage levels of teens. Anecdotal evidence says that teens are abandoning Facebook for apps like Snapchat. When asked about engagement for different demographics, Facebook's CFO David Wehner said the company had nothing to report on specific cohorts of users. So what's the good news? Facebook's billion user march! Each month, 1.35 billion people log into Facebook; 864 million are daily active users, which is up from 829 million in the second quarter of 2014. If you prefer percentages as a metric, 64% of monthly active users log on to Facebook every day. Revenues? How about $3.2b in total revenue and $766 million in free cash flow in the third quarter. Advertising. Facebook turned in a 247% increase in ad prices. If you are a company without a mobile strategy, you better get moving. Over a billion users, 1.12 billion users to be exact, use Facebook mobile each month which is up 250million since last year and 703 million use Facebook mobile each day, a 40% growth year over year. Mobile is 66% of ad revenue up from 49% during the same time last year. If these numbers about mobile don't move you, chances are your business could go the way of the Dodo bird.
