Skype: Mobile usage continues to increase thanks to Skype’s wise investment in apps and a mobile platform.

Facebook: Now tops 629 million registered users with almost 250 million people accessing the site via mobile.

Qzone: China’s version of Facebook, Qzone, is experiencing supernova-like growth with 480 million registered users.

Twitter: Broke the 200 million registered user mark with nearly 40% of people tweeting via mobile.

Email: Hotmail still dominates email, but Gmail is gaining fast.

Yelp: Yelp is topping 50 million unique visitors per month. Its move to team up with OpenTable earlier this year will only increase its relevancy.

Foursquare and Gowalla: These geosocial specialists are still growing, but growth seems to be slowing down a bit.
