67 feels different. The vim/emacs gag feels authentic in the way that someone surrounded by cs/vim/emacs/unix culture would want to stir the pot playfully. "Do a barrel roll" similarly feels like something culturally relevant to whoever implemented it.

No one involved in implementing 67 is of the age group where it was culturally significant so it feels like trying to jump on a bandwagon to feel relevant. And also making the screen shake was the best they could come up with?

Or I'm just looking for excuses to justify my idea that old Google was cool ̄\_(ツ)_/ ̄
