Is M$ B0rking again? The linked article's focus seems not totally improbable given my experiences of similar.
The summary flap seems another case of browser and server interactions blocking files. Remember the Opera B0rking fiasco?

To my take stripped of rants,FUD,and the usual other chuft - There is ample past history to support non-neutrality as being at work. Read the article and responses. Can we independently sanity check this both from our Linux boxes and any Ms ones we have to use?
