I stumbled at one very questionable blog post that received huge attention from bloggers all over the world: http://www.sutor.com/newsite/blog-open/?p=2031
Blog writer is commenting on whether person should use or not Office 2007 implementation of OOXML or not, suggesting at the end that it would be the best for the users to stick with old binary formats??
Based on the fact that OpenXML is based on XML format and author’s consideration “...I am now wondering whether it is safe to continue using HTML…” above mentioned statement is not very credible and raises the questions if author understands what he talks about, at all!
In mean time, excellent resource for all of the rest that are willing to develop applications that use OpenXML is http://openxmldeveloper.org/default.aspx
