.NET Nightly 40 or Longhorn RSS, Aero, and more Indigo

I tried to come up with some stuff that was not PDC related... but oh well...

Longhorn Dev Center RSS - A RSS feed for the hotest new dev center on the block.
Aero User Experience Guidlines - Cool stuff in here, some of the best screen shots of the sidebar.
A Guide to Developing and Running Connected Systems with Indigo - Don Box talks about everything that is the Indigo "state of mind".
