So what exactly is the point of this link? Can we follow this course online?

My guess is that the point is that there will be a functional programming and Haskell class taught by well known Haskell folks.

Is the site supposed to work? Most links are broken.

lectures have not been done yet. The course will start at the end of september, I don't think the material will be published in advance

This class looks really intense. I'm so excited for this -- just look at that syllabus!
