Just some quick fan mail... I know Racket has tremendous reach to students via HtDP, etc. But I also used it for a course I'm currently teaching on Coursera for 2 of the 7 assignments, the 2nd of which was just due. Overall, we handled a few thousand submissions for each assignment with basically no glitches. (Okay, okay, we tripped across and confirmed one compiler bug, which we've reported.) Much appreciated!
And naturally I said nice things about Racket in the course. (And naturally, any of you in my shoes would have done some things differently. :) ) Finally, as will surprise almost nobody, the installation instructions for SML N/J and Ruby 1.9 were about 6x longer and more error-prone. Sigh. --Dan
