Alas, not to bring ageism into the discussion, but I'm gonna bet that probably just means you were born in, what, the late 90s or later?
Journalism serves a vital function. It's called the "fourth estate" for a reason, and should serve to enlighten the public on the goings on of the government and the world. Journalism is one of the forces counteracting government secrecy and surveillance. Hell, journalism is what brought the Snowden revelations to light to the general public.
To do that well, you need professional writers, researchers, and fact checkers. No, a casual blogger is not a journalist. Twitter is not journalism. Tumblr is not journalism. At best those are news. At worst, gossip.
Unfortunately, we now have an entire generation who doesn't understand what real journalism actually looks like. It's a damn shame... remember, journalism brought down Nixon and helped end the Vietnam war, among many other things. Real journalism can be immensely powerful as a medium.
It is not horseshoe manufacturing.
