Which brings us to the OOXML issue. That ugly acronym is Microsoft's response to the demand for "open standards", and in their new style of choosing the most generically offical sounding name possible, stands for "Open Office XML". Especially funny when you consider that one of their biggest competitors in the office software arena is called "OpenOffice".
And, inexplicably, the ISO has chosen to approve the OOXML standard, proving that they do not understand the word "open", and also that they seem to have temporarily misplaced the concept of a "standard". There has been a great deal of protest and manly geek-tears shed over this debate, and the internets have not been kind to their decision.
Go read the whole thing. An informed opinion from a nerd is always worth the time, especially in this case.
