3 major powerhouse networks for college

Hello !  Guess what I got started on the paper , you know, the one that has to be1k words and in collaboration with my other two wonderfully intellegent classmates.    Im writing about the 3 major social networks, facebook, Linkedin, and Twitter and how they can immensely benefit college students with their education, job searches, and just the vital importance of connecting with the world in general.   Although they maybe famously know for their social significance personally but will serve as social platforms to spring us to the next level of public recognition.  ....teacher wants our attention.. more later.
