As noted in his latest blog entry, Chris Shiflett and the Pro::PHP podcast are again collaborating to bring the listening community more "Ask Chris" shows.

It's been a few months since Episode One, but thanks to Marcus, Ask Chris is back on the air. The format is a bit different - instead of doing separate shows, we'll be doing a short segment at the end of each interview.

This interview is with David Sklar of Ning. He and Marcus discuss Ning, of course, but David also provides some good perspective on the state of technology and how the definition of a programmer is becoming more and more inclusive.

This episode of Ask Chris is about email injection, a topic of growing concern for PHP developers.
