David Ebersman,the chief financial officer,recently raised the concerns that the dominant population of the social network–the teenagers,are less active on the Facebook.

“We did see a decrease in daily users, partly among younger teens,” Ebersman admitted.

The survey among 30 countries revealed a decline from 76% in the first quarter to 56% in the third quarter in 2013.

Where are the teenagers flocking to?Mostly the Wechat,Instagram and Snapshot.

The mobile chat services like Wechat and Whatsapp are more favored as the messages are passed more instantaneously.And other apps like Instagram and Snapshot have the  specialized advantages of photo-processing and photo-beatifying.

The trend is that teenagers are more likely to chat and talk through the mobile apps instead of on the website.

But still,the instant messaging conveyed through Whatsapp and Wechat is based on the small groups of friends they mostly know from the real life,while Facebook focuses on the virtual social network.Therefore, they can coexist.

In my perspective,teenagers are still using the fb in the social life while the numerous social networking apps are slowly taking them away from the fb. Teenagers are faced with multiple choices to spice their life up.
