WordPress user and hacker since 2004, I've watched WP grow and evolve since version 1.01.
I made a number of popularish plugins and regularly write about WordPress on my blog.
I have been an official judge in the WordPress Plugin Competition.
In 2011 I have written <a title="Plugin Dev Book" href="http://amzn.to/plugindevbook" target="_blank">Professional WordPress Plugin Development</a>, *the* book that explains it all.
