New York Magazine has this terrific bubble graphic, that is far prettier than it is informative.
Abnormal returns call it a “bubble in calling things bubbles;” That is a phrase I will take some credit for — I first used all the way back in April 2005 in BusinessWeek: A Bubble in Bubbles? (never it saw it before then anywhere else).
Please use the comments to demonstrate your own ignorance, unfamiliarity with empirical data and lack of respect for scientific knowledge. Be sure to create straw men and argue against things I have neither said nor implied. If you could repeat previously discredited memes or steer the conversation into irrelevant, off topic discussions, it would be appreciated. Lastly, kindly forgo all civility in your discourse . . . you are, after all, anonymous.
