You seriously could not make this type of stuff up. Microsoft released an update to Silverlight 2 recently. Did they call is SP1? Nope. Did they call it anything related to ANY other product strategy they have on the planet? Nope. Silverlight 2 GDR 1 ( Really ) Yep. GDR = General Distribution Release. Because we see that term all the time, right? I mean normally CTP (Customer Technical Preview), goes to RTM (Release to Manufacturing). It reminds me of the part in Good Morning Vietnam (movie starring Robin Williams) where they all were making fun of military acronyms.
