Yahoo’s Open Graph app grew by 5.7 million DAU this week, Microsoft Live by 500,00 DAU and Pinterest by 300,000 DAU. Pinterest has gotten a boost from its new Open Graph integration that has been generating prominent stories in people’s News Feeds (see image below). Dating app Niik was another app that made the list. There were a few birthday apps that ask users to invite friends before promising a customized calendar with friends’ birthdays. Similarly, there were a group of  greeting card apps that create an integration displaying a users’ friends with upcoming birthdays and enable the easy sending of virtual greeting cards.

Game apps that made the list came from Zynga and others. Zynga’s Hidden Chronicles grew by 1.3 million DAU, Scramble with Friends by 300,000 DAU and CityVille by 200,000 DAU. Then there was Diamond Dash,   المزرعة السعيدة and  開心水族箱. The rest of the list included page tab apps for HTML, iFrames and more.
