I've been meaning to write about what I call "the outrage economy" forever now, but now Peter Cohen at iMore has done it for me:
These days the Internet Rage Machine swings into overdrive at the drop of a hat. Everyone uses almost every excuse to get angry about whatever they can. Because rage drives traffic, and traffic can drive revenue when you run a web site that's dependent on page impressions and unique visits to generate traffic for advertisers. For some people, it's all about going viral and getting eyes on your pages.
There are very real reasons to turn on the Internet Rage Machine. There are real problems in the world and sometimes lots of people yelling via Twitter is the only way to get attention. But time and attention are limited resources, and I cannot understand wasting them on something as trivial as an Bono and The Edge.
