In our half-yearly review of the top Internet trends of 2012, there's been a common theme: mobile is the main driver for all of them. The Visual Web (Instagram, Pinterest and similar image-focused apps), the Consumer Cloud (Evernote, Dropbox, iCloud and others), social video apps (Socialcam and Viddy) and video on tablets (BuzzFeed, Flipboard and others). Each of those trends are popular in 2012 because of smartphones and/or tablets.

Microsoft's Mobile-Centric Windows 8

Microsoft is a giant company built from a PC operating system: Windows. But the latest version of Windows, Windows 8, is heavily influenced by mobile and designed to integrate across devices.

The Windows 8 user interface - labeled Metro - is based on the mobile paradigm. It has touchscreen functionality and a new tile-based Start screen inspired by the Windows Phone operating system.

Microsoft has also made it easier for developers to create cross-platform apps. The Windows Phone 8 operating system features something Microsoft calls "the common core," which is a shared set of code between Windows Phone 8 and Windows 8 on the desktop that will allow developers to write applications for Windows 8 and easily port them to Windows Phone 8.

Facebook's overall monthly active users is 901 million, so that's 55% of Facebook's monthly active user base who access the social network on a mobile device. That's got to be a strong indicator of which direction mobile traffic is headed!
