Yesterday (April 14) I was interviewed by an Australian broadcaster in connection with
Blogging Heroes. It happened that the evening before I had seen an interview with Ted Koppel on BBC's American service. (Yes, he left Nightline for the Discovery Channel and the BBC.) The subject of the discussion was blogging--specifically, the legitimacy of news from blogs.
As expected, Koppel came out supporting mainstream media as superior to blogs. He didn't mount an attack on blogging, but he did make one good point, which I brought out during my interview. The big difference between conventional news media and blogs can be found in the fact that most blogs do not vet their news. It is true, of course, that non-vetted items make it through to newspapers, magazines, and radio and TV broadcasts. But blogs tend to go with far less verification than mainstream media. And "citizen journalists" often don't have the background necessary to see the story behind the story.
This being the state of things, it is a wise course to verify news with multiple sources. But that applies not just to blogs, but mainstream media, as well. Mainstream sources are known to to slant coverage and omit facts, which is sometimes more dangerous than getting the story wrong.
