Well, it's actually February 1 already here in Delhi. :-)

Here are three great links about Office Open XML and related topics, each worth reading closely:

Rick Jellife: "What is "Contradiction" of an ISO Standard?"

Jonathan Allen: "Fire and Motion: What OpenXML Means to IBM and Lotus Notes"

Miguel de Icaza: "The EU Prosecutors are Wrong"

(Thanks to the anonymous poster who brought that last one to my attention.)
