I was stunned and delighted to see Metaprogramming Ruby topping the Amazon.co.jp chart for English-language computer books. At one point, Amazon.co.jp even listed Metaprogramming Ruby amongst the 50 best selling English books overall! I could get a good sight of Dan Brown and Harry Potter from there (not to mention a lot of Michael Jackson biographies). It didn't last long, but it was nice to hang around with the big boys for a few hours.
As a first-time author, I couldn't have asked for more. To all the people in Japan who bought the book: thank you! Stay tuned, because there might be more news for you in a few months...
