I have been here for more than 2 months, and used google reader to obtain latest news, literatures alert for more than 1 months. I really shocked when came accross with news reported about the usage of facebook.

Undeniable, facebook serve as a platform for me to keep in touch with my fellow buddies, their latest info, and so on. Furthermore, we also can make fun with picture uploaded. However, I quite suprised with the impacts of facebook here, after I read news from BBC. I tried to type "facebook" of my google reader, and found the following articles. For more information, feel free to read the following articles.
