By some strange twist, I've been comparing(writing same project in) Lisp(s) lately and I have to admit that I find your post very timely. The more I force myself to think about programming at ever increasing levels of abstraction, the better my programming skills and observations seem (hard to verify) to become. Contributions like yours can not help but help. Why some day I may be able to read "Escher Godel and Bach" closely enough to understand the jokes!

You get to love scheme after a while. It's so simple. Not necessarily practical, but a thing of beauty :-)

If I have to choose(just for me) between common and scheme, clearly I'll pick scheme. That said, if we are talking production code and a many programmer setup, I'd probably pick common. Mostly I'd just as soon avoid picking. At the moment I'm writing my PGN parser code in newLISP--- and having more fun than should be legal. Will have to go back and change (update) my CPAN modules based on things I've learned in the comparison. Can't wait until I move on to common and scheme; I'm sure I'll find even more code for thought...

I really enjoyed browsing your book the first time you mentioned it here. It's a real shame that you felt the need to involve javascript in the mix. Now when I follow your link, and click html, I get a blank screen :(

I'm really sorry about that.
The js was added for a valid (imo) reason - to make the display of footnotes unobtrusive and natural; the behavior degrades to a plain link if it is disabled.
Maybe you have an older js implementation enabled?
edit - should have mentioned, the js only controls the display of the footnotes.

With or without JS enabled, when I click the link bottom-left of the title page, it takes me to http://billhails.net/Book/front.html which comes up entirely blank using my preferred browser (Opera). I viewed the source and saw the reference to book.js and attributed the problem to that.
I just sparked up an (relatively ancient) version of Firefox and the page loads fine there. Looking at the JS, I suspect DOM differences for Opera vs. FireFox.

I believe I've fixed it, at least the Opera that I tested that was hanging no longer does so. Problem wasn't the javascript per se, it was the script tag that has to be in the form <script ...></script> e.g. <script .../> won't cut it for older browsers.
