I am also looking at this stock. But I am more concerns on the change in fundamentals. There are increasing concerns on privacy issues and it affect the moat of targeted marketing campaigns that facebook offers to marketers. We are sessing increasing number of advertisers pulling their budget out from facebook as they see decreasing performance from their ads campaigns. E.g. they are now unable to reach apple users. What are your thoughts on this? I think this privacy trend will only get stronger as time goes by. Does facebook has other revenue sources?
