One thing that stood out in Facebook's relatively by-the-books earnings call is how few ideas Facebook seems to have outside of "make it like mobile." That's probably not the best news for you.
Facebook's primary focus today was its effort to convince advertisers that Facebook ads aren't a waste of money. That's been a big problem for the company (naturally, given that 90% of its revenue comes from advertising), and mobile has been a particularly sticky wicket. Its main source of revenue came from ads—poorly performing ads, but ads—that were on the right hand side of the page. But you can't do that on a 4-inch screen.
