As I was using Google reader to look through blogs I subscribe to, and blogs my friends thought worthy of sharing I somehow landed on <no>ooxml which, if you have not been following is a good response to what appears to be Microsoft abusing an international standards body. I would say the petition on their site is worth signing.
More importantly that site led me to another site that is petitioning governments in general to adopt a better mindset towards software. The Hague Declaration is good stuff, and articulates many of my ideas about why open source matters and why people should care. Awareness is a big part of bringing about change. If you like the petition at least encourage people to read it.
