I stumbled upon AdvertBoy's blog tonight and I'm impressed with his approach in using Silverlight.
He impresses me because he's looking around at what he see's as being "Cool" and then tries to emulate this via Silverlight. This is a good thing as if with more and more RIA Producer's approaching Silverlight like this, we will all learn something new.
I also noticed he's taken the approach of producing what he calls "BlendCandy", essentially it looks as if he's re-creating some icons via Expression Blend. This a market I'm waiting to see flourish, as with XAML one is able to potentially create some profitable products to hand to the next wave of Silverlight / WPF developers out there (whom may not have a designer on staff).
I love finding these types of blogs!
