Two days after is started shipping, my new "Sams Teach Yourself Regular Expressions in 10 Minutes" made it onto the Amazon.com Bestsellers list, debuting at #3 in the "Computers & Internet" category. (#1 is a title on Mac OSX, #2 is on Adobe Photoshop, #4 is on Windows Server 2003, quite a diverse list). List is at Books, Bestsellers, and then select the category from the list on the left. Cool! :-)
