I feel like the 'book is having trouble adding new users. This is probably another stab at inflating their numbers for their Q earnings reports.

There are a limited number of users out there. Emerging markets aren't growing fast enough and aren't going to be strong soon enough to support the FB's growth rate. It seems investors rely a lot on the daily users metric as it translates into more potential advertising revenue.

This acquisition will certainly help that number, daily active users.
