There is now DirectWrite content in MSDN as part of the Win7 beta documentation.    The content includes overview docs, API reference and sample code.  If you have downloaded the Windows 7 beta, try out the DirectWrite APIs and send us your feedback either on this blog, or via the MSDN feedback dialog box, the “Send comments about this topic to Microsoft” link, as well as the Community Content section at the bottom of each topic.
