#1) I don't get this one. WPF/Xaml/Silverlight is the best thing to come out of Microsoft in years. I really can't imagine doing front end development in another tech.
MossyBlog is full of shit. Who cares if Silverlight/WPF merge? Do you really think they would push Silverlight as the dev platform for their new phone OS if it was going to be replaced by html5?
