There are a number of FAQs that are comming through the Silverlight forums and so we created a wiki page up on channel9 to list the FAQs. http://channel9.msdn.com/wiki/default.aspx/Silverlight.SilverlightDevelopmentFAQ

 And best of all it's a wiki so YOU feel free to add your own FAQs to the list. We're planning on linking to this wiki page from the SDK and from Silverlight.net so, down the road, this page will be pretty discoverable.
