Maybe in IT college is overrated, but when is something about i don't know let say medicine.... If I were sick I'll pay the best doctors I could, I won't be looking for somebody that has a fancy ad or millions of likes or followers or pluses and does not have a degree in medicine....
Maybe in the verge of death I'll look for a shaman...
Overall my point is that college is not overrated for all the careers. The article did not focus only on IT....
I like that I don't need to "register" or login/password.......I don't know how this will work with the mobile app you're working on, maybe register the "pages" in the app....anyway
