Give Mark Zuckerberg credit – he realized Facebook was behind when it came to mobile and he forced his company to adapt quickly. It’s reminiscent of Bill Gates coming to terms with the web back in the 90s.

The mobile story for Facebook isn’t a new one, as the company has been killing it in the mobile space for over a year. But the results keep improving. The latest earnings report is spectacular, as we see Facebook becoming a must-use platform for advertisers on mobile.

As a contrast, consider all the problems facing Twitter, and you see one company with a clear focus and the other without much of a clue.
