Speaking of @jao, a topic that came up last night at @fossandcrafts's Scheme Workshop was Gerald Sussman's comments on why MIT stopped teaching #SICP as an introductory course in 2009. Here's a longer blog post by @jao from #ILC09, where Sussman made these comments, with input from no other than Dan Weinreb (rest in power), and links to other articles on the subject (like Andy Wingo's report from the event).
