Every single day I see "reputable" news sites put out headlines like "Twitter outrage over [X]" and I think this is why journalism is dying. The "man on the street" piece has a time-honored place in journalism, but previous generations understood that the opinions of random strangers are not, in and of themselves, NEWS. They were fluff pieces and human interest bits, not headlines. They constitute opinion at best, and usually closer to gossip most of the time. I don't blame Twitter itself, per se. But it is easier for journalists to find opinions than to find facts, and that has certainly led to a degradation in quality of news stories and a near total loss of understanding of what constitutes bias in journalism.
