Library of Congress and Microsoft

The Library of Congress has decided to use Microsoft’s Silverlight to build their new website. LibraryThing has something to say about it:

Most disturbingly, users are locked in, too: anybody using an iPhone, an old version of Windows, any version of Linux, or any other operating system or device not supported by Silverlight will be unable to use the Library of Congress’ new website. How is that compatible with the principles of democracy or librarianship? It’s taxation without web presentation. And how exactly is that a quantum leap forward?
