Somebody submits a story summary to slashdot
Slashdot runs it
People read it
this is where most mass media stops. People enjoy the story and go on blissfully ignorant if the proposed idea is stupid. But sometimes you get some wicked smaht people commenting on slashdot.
People think about it
Then you read comments
and realize the "why didn't I think of that" idea might be stupid
So if you like a story summary on slashdot . . . don't read the comments!
