A new site from the creators of LearnVisualStudio.Net have launched LearnExpression.com! The site will offer video tutorials for all of the new Microsoft Expression products. They have done well so far in creating a community surrounding the LearnVisualStudio.Net site with forums available for the lifetime subsrcription members to converse and find more information. I suspect they will be doing the same here.

They have really done well with the streaming via Camtasia and you can see a free video here.

Since Microsoft has implemented a lot of this interface into Visual Studio Orcas, you might want to check it out!
