Signed up for https://www.coursera.org/learn/programming-languages . Watched the intro, and can't remember feeling so hyped about an MOOC.
"There's something deeply artistic and elegant in
the way programming languages fit together and I want you to stretch your mind, and
I want you to look at this course as a fresh way to look about software.
A fresh way to think about programming that you've never thought about before.
We're going to make you uncomfortable.
We're going to do things in a strange way."
Quite a claim.
