I wrote an article for NETTUTS that was published today. It's called Building a Better Blogroll: Dynamic Fun with SimplePie and jQuery. In it, I make up a "widget" for pulling in recent headlines from the Envato family of blogs which you can switch between using the Coda Slider plugin for jQuery.
I was interviewed by Charles Stricklin of the WordPress Podcast on Episode 44. It starts about 58 minutes in. We talk about that series I did on Designing for WordPress.
