The appetite for journalism
I watched Journeys with George, a documentary about George W. Bush's 2000 presidential campaign, and as I watched the press corp deal with both camaraderie and competition, Alexandra Pelosi (the filmmaker), says this:
"I realized then that while I have the appetite for journalism, I don't have the stomach for the cannibalism."
Replace "journalism" for "blogging", and you pretty much have my opinion on the blogosphere.
