I would say resources to learning silverlight would be a big reason it hasn't gained traction. After the basics it's a real struggle to work out how to do a heap of things, the answers usually seem to be buried in blogs and comments if at all. I find MSDN equally hard to work out for other technologies as well, but at least there are other resources out there, with silverlight sometimes the only mention of a feature existing is on a developer blog.
