Microsoft’s Office Open XML (OOXML) document format has received ISO approval and is now an official ISO standard. Wonderful. Since it’s an open standard, you’d think Microsoft won’t be able to lock in users the way they have in the past. I have every confidence in their ability to somehow screw us over. Perhaps they’ll get a good head start through sheer obfuscation. The document describing the file format is a mind-numbing 6000 pages in length.

Reading the comments on the Slashdot story, I think user darkfnord23 has a keen insight:

Anyone using this standard for anything deserves a punch in the face.
