I just saw that Document Sciences has also joined the OpenXMLDeveloper.org site (story here). It's been a pretty fun week seeing all the folks joining the community. It's pretty suprising that after only a week we already have over 250 registered users and over 40 companies.
I'm really excited about the value this site will bring to folks, especially once the public Beta 2 comes out in the next few months. There are already a number of good articles and discussions up there, and it's only been a week 🙂
