As many have said, just.. thank you for everything over the years. I wish you nothing but happiness and success in your life, and I'm sure your family will be glad to have you around a bit more:) We'll still always be just a click away! We love you!!
People also forget that, as much as this sucks, it's worth it to not cause a panic too early when maybe they don't have all the details themselves. I would rather hear the solid facts in a calm manner a little later than a panicked "um, some of your information was stolen, we're still figuring out the scope of this..." on zero day.
+1 for this. Silverlight hasn't been around that long, they obviously were fairly recently able to learn something new. It's understandably frustrating to lose all that work, but they can certainly do it again and move on. The tech world is ever-changing, and we have to be too.
