This week we interviewed the, quite prolific Anne van Kesteren on CSS, XHR, and other Web standards.

A breakdown of the contents of the interview, by Dion:

Anne van Kesteren is an Opera Software employee who is deeply involved in the standards community. Just take a look at his page on the WHATWG site and you will see the many specifications that he is actively working on, such as:

• access-control
• XMLHttpRequest
• XMLHttpRequest2
• cssom-view
• css3-mediaqueries

He is also interested in many other specifications such as offline Web apps, the Selectors API, and beyond.

We got to sit down with him (virtually) and discuss both high level issues such as the current state of CSS, down to the brass tacks of particular APIs such as access-control, CSS3 Media Queries and XHR, and even look to the future with technology such as WebSockets.

You can download the podcast directly (OGG format too), or subscribe to the series, including via iTunes).

There are some nuggets that I didn’t know of, such as the agreement with Microsoft to at least use access-control (as XHR level 2 does) for their competing XDR proposal.

Finally, with John Resig from Mozilla Corp, and Anne from Opera, there is some healthy debate on the roll of market share and minority browsers.
