I was doing some SEO research into how well the Silverlight name is positioned. I was surprised that http://www.silverlight.org goes to a Microsoft placeholder site but http://www.silverlight.com/ goes to an Apple placeholder.
This is probably a MAC user that owned this domain its whois has a contact with an @mac.com address. I wonder if they just his it big in a domain sale.
UPDATE: Well someone worked quickly it now has some business information and products.
