I'm like the OP in that I've set up the environment and am up to Ch 12 in Practical Common Lisp. Plus it finally motivated me to learn emacs after a couple of decades of vim. The extract from the Land of Lisp makes me think I might enjoy Scheme more, since I'm just learning Lisp at home for fun. Can you recommend a particular online learning resource? I've had a quick look at MIT's videos of their lecture series, but I've just run out of spare disk space on the laptop, so storing a few GBs of movie is out for the moment. If there's something like PCL for Scheme, that would be great.
