content: Office Open XML is bullshit. They packed the standards commission meetings around the world with MSFT shills to push their own technology. Show me a tool that can easily copy/paste content from word  without formatting issues. C# runs only on Windows and is tied to either a free shitty or expensive IDE. If Microsoft wanted to be "free" they would adopt standards instead of rolling their own.  Mono sucks and isn't well supported. bla bla bla my flavor over your flavor.
