I choose Facebook cause this dynamic virtual platform not only bonded peoples to peoples worldwide but also creat a craze among those peoples who doesn't have any any highly qualified education background. Such as a tea seller in my area who hardly read bangla language before 3 months ago but when I opened a fb account for him and show him how to use facebook. After that its a magic right now he is not only use Facebook he also know how to go other sites by writting the web address on a browser. So,in this method Facebook helped millions of peoples worldwide who never ever thinked that they are also capable to enter in the virtual world of net.So,Facebook is the pioneer in this sector.that's why I like Facebook.
