|When enough cockamamie ideas are peddled as the next big thing, maybe it's time to run for the hills. Facebook could be a case in point.|
Growth in use of Facebook through our mobile products, where our ability to monetize is unproven, as a substitute for use on personal computers may negatively affect our revenue and financial results. We had 488 millionWell, at least it's there in black and white, and no investor can say they weren't warned. A famous anonymous phrase of the last Internet bubble was, "It's different this time," which was sage foresight at first, then, finally, the ultimate statement of hubris. I can say this much with confidence: It's absolutely no different this time.
monthly active userswho used Facebook mobile products in March 2012. While most of our mobile users also access Facebook through personal computers, we anticipate that the rate of growth in mobile usage will exceed the growth in usage through personal computers for the foreseeable future, in part due to our focus on developing mobile products to encourage mobile usage of Facebook. We have historically not shown ads to users accessing Facebook through mobile apps or our mobile website. In March 2012, we began to include sponsored stories in users' mobile News Feeds. However, we do not currently directly generate any meaningful revenue from the use of Facebook mobile products, and our ability to do so successfully is unproven. We believe this increased usage of Facebook on mobile devices has contributed to the recent trend of our daily active users increasing more rapidly than the increase in the number of ads delivered. If users increasingly access Facebook mobile products as a substitute for access through personal computers, and if we are unable to successfully implement monetization strategies for our mobile users, or if we incur excessive expenses in this effort, our financial performance and ability to grow revenue would be negatively affected.
