It is kind of sad that they advertise non-free Software companies there: They ask me to install Adobe's flash player, Microsoft Windows' media-player, Apple's Quick Time or Nullsoft's Winamp. Can you imagine signs at the highway saying: "To use this road please use a Chrysler, Hummer or a Toyota. Your Government.
I think it is not ok for the government to advertise the business modells of some companies on their website. Especially I am against the government advertising the business models of non-free software companies. (Perhaps I would understand it if those companies were German or European.)
And you might already guess it: OGG vorbis is not in the list of audio format. I wrote them a comment about this. Let's see what happens.
