Christmas continued to feature prominently on our list this week, as evidenced by several apps used to send greeting cards amongst friends. Calendars were also popular, however, as well as apps that cull profile data for 2011 retrospectives and publish corresponding photos to the feed.
The apps on our list grew from between 124,400 and 609,200 MAU, based on AppData, our data tracking service covering traffic growth for apps on Facebook. We define emerging applications as those that ended with between 100,000 and 1 million MAU in the past week.
