The article links to the wrong URL for MSN's experimental RSS reader. The right URL is http://www.start.com/myw3b/ and it works just fine in Firefox as well as IE.

If you are interested in the developments of the RSS reader you can check out some of the blogs by the folks working on the reader such as Steve Rider and Sanaz Ahari.

I have found Extreme Programming techniques to be very useful. I do much less debugging now, because I write unit tests as (or even before!) I write the methods. I use the JUnit framework for all the Java code that I develop.

I'm sure that debugging technology can and should be improved, but I think that better development methodology reduces the need for debugging.
