Its the first annual Document Freedom Day!
Document Freedom means open standards and free document formats. Take a few minutes to check out what this means to libraries, society, and to you.
For me, well, I have been a fan of open standards for years (I do too much xhtml/css to not appreciate standards), and I also feel that the Open Document Format (ODF) is not only more flexible than closed formats, but I like that I can rename the file with a .zip extension, then open it up and see (and extract, if needed) all the separate elements that make up the document.
