O'Reilly has opened a site called Beautiful Code with discussions and articles about the eponymous topic, partly by the authors of the eponymous book. Sample openers include "One of the reasons there's less beautiful code in the world than most of us would like is that academic computer scientists don't actually seem to care much about it...". And they've published an article of mine about the Reflection API that covers this topic in some detail.

There is also an interview with the book's authors on Safari.
