I don't usually post news etc. as I think there are plenty of other people doing a good job in that area.
And why is this sooo exiting, well for one thing it's one step closer to being RTW (Released To Web) it's also bound to have some bug fixes and possible some new features. However the really big deal is that it comes with a commercial Go Live license! So now we can finally start using Silverlight 2 in real world projects for clients.
Aside from looking forward to starting building real apps in Silverlight 2 myself, I'm also very much looking forward to seeing what other people will come up with now that it's commercially available.
Update: The folks over at the Silverlight SDK Blog now has a post that mentions some of the changes that we'll be seeing in Beta 2.
