Andrew Nacin (@Nacin), a lead developer of WordPress, spoke at WordCamp Portland 2011. He talks about everything inside WP_Query and more. This is a developer-heavy talk, so it’s not for the faint of heart. If you love code, click play below and listen to what Andrew has to say.
It’s a great talk, but I wish we would have been able to see the screen to follow along better.
UPDATE: Thanks to Ben, in the below comments, he spliced up Andrew’s video and slides together. I have updated this post to include the video.
