Spirit of our time?

Browsing today's Memeorandum,I was struck by the way the stories seem to all move in a negative direction. Perhaps the main meme of our age is skepticism. News isn't news if it doesn't make somebody look bad, or question what we thought we knew. Is this really what people need from news media? What's so bad about reporting the good we're doing around the world? Is this what journalism has become, just a whiny old grandma who casts a pall over everything in life? If so, the sooner we replace it as a profession, the better off we'll be.
