Half a year after my WordPress plugin development book was published I am pleased to see that the book found it's audience and it's selling at a satisfactory pace. The plugin ideas for the book came mostly from David Barnes, who was also my editor at the beginning and provided valuable tips (hint: he is also the guy to contact if you have a book idea). The plugins were fun and useful, and today you may have heard about WP-Wall, Snazzy Archives and Insights WordPress plugins.
