Stanford CS enrollment increase "downright scary"
  When expensively educated, fashionable young graduates
  start showing up in your field, you're in a bubble.

I fully attribute the increase to The Social Network movie coinciding with the ballooning of Facebook's market cap.  Flipping tech startups is the hot new get rich quick scheme.  Just like flipping houses and subprime mortgages before it.
