Early November Ebermsan, chief financial officer of Facebook, confirmed that users are becoming less active. As the largest social network in the world, Facebook is losing users because of mobile chat services and photo-sharing apps, such as WeChat, instagram and Snapchat. Ebermsan referred data of usage number from first to third quarters of 2013 which the total number of active teenager users in 30 countries dropped by 20%.

“There is a very clear story with the big winners being closed messaging and video-and-photo sharing apps,” said TomSmith, CEO of GlobalWebIndex. “This is something that could be particularly harmful to Facebook because its core value lies in peer-to-peer community, messaging and photo sharing, but has less of an impact on Twitter because Twitter plays a greater role in accessing real-time news, interacting with TV or following celebrities.”

The article mentioned about WeChat, Chinese messaging platform with both Chinese and English versions, saw an extraordinary rapid growth about 1,021% of active teenager users between the first and second quarter even though most of its growth came from Chinese Communities.

In my opinion, the decreased users of Facebook are reasonable. I use both Facebook and WeChat. I personally prefer WeChat because it is more convenient and easy use than Facebook. It is a very small app which users can contact their friends in either voice message or text message, share your moments anytime, and check emails, which users can not do on Facebook website at the same time.

The change of customers’ preference in mobile service drives the change of composition of Facebook as well, and we can indicate it by its large growth in mobile app which up to 69%.
