Microsoft launched Project Rosetta today. To quote the site:
Project Rosetta is a site dedicated to helping designers and developers build applications in Silverlight while taking advantage of skills they already know.
It seems like a laudable effort to try and find a place to help people (though the site seems to really be focused on Designers) create great Silverlight 2 applications. Of note, I particularly liked the From Flash to Silverlight article that is up on the site. Let me know what you think!
