How long has this been going on?

OK, readers (all three of you), why didn’t anyone tell me about Junk Charts or Mahalanobis?  I had to read about them from Gelman…

Mahalanobis is to economics as Gelman is to social sciences; I expected
to get some great lecture material and student project ideas
there.  Junk Charts is going to become one of my faves, since it’s
the good, bad, and ugly of statistical graphics.  Man, this guy
does not like donut or pie charts!  (Mmmm, pie…)
