Facebook (FB) has filed an amendment to its S-1 in which it reaffirms its need to improve mobile monetization. Facebook's ad growth is no longer keeping up with its daily active user growth (+41% Y/Y in March), and the massive increase seen in Facebook's mobile user base has much to do with that, given it has only begun selling mobile ads. The fact much of the user growth now comes from emerging markets where Facebook's ad sales are limited is also likely part of the problem.
