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.)
