Kevin Rose, who just took over as CEO of Digg from Jay:
Framing content with an iFrame is bad for the Internet. It causes confusion when bookmarking, breaks w/iFrame busters, and has no ability to communicate with the lower frame (if you browse away from a story, the old digg count still persists). It’s an inconsistent/wonky user experience, and I’m happy to say we are killing it when we launch the new Digg.
