Drupalcon 2008 Boston
It was a pleasure to attend the 2008 Boston Drupalcon and meet some of the many Drupal developers who have read Pro Drupal Development. One of the goals of the book was to bring smart people into the Drupal community -- people who don't have to be told how to set up PHP, or what CSS is. What they need is a technically detailed and accurate description of how Drupal works. This allows them to get up to speed quickly and minimize the time it takes to become productive with Drupal. From the conversations I had in Boston, it appears to have worked, and that is gratifying.
The second edition is coming along nicely.
