I had a great time and learned a bunch of great stuff this weekend at wordcamp montreal. Matt Mullenweg was even in attendance.
I ran across a good set of articles on mastering WordPress. There are four articles in the series covering tips, tutorials, hacks, themes, plugins and best practices from some of the leading WordPress developers. Part One: Mastering Your Theme Hacks and Techniques Part Two: 45+ Must See WordPress themes Part Three: Powerfull List of WordPress Lifesavers Plugins Part Four: Elegant and WordPress Designs- Best Practices
