Lachlan caught up with Wilhelm Joys Andersen, Head of Core QA at Opera Software, who describes a secret plot to reveal bugs in web browsers and force them to obey the specified rules. As the world becomes overrun with test cases, he still claims it’s not enough.

Anne van Kesteren sat down with Simon Pieters to talk about the impact of XML on the mobile web, who gave a surprising insight into its failure. They discuss the level of support for XML vocabularies in mobile browsers, and what mobile browsers have been forced to do for compatibility with legacy content.

Anne caught up with Lachlan Hunt, editor of the Selectors API specification, in Oslo, Norway. Lachlan describes the purpose of the spec and who’s implementing it, as well as outstanding issues and fancy new features that the WebAPI Working Group wants to add in due course.
