To use Silverlight as an example, I think it sucks. It's bloated and I don't get it. I'm tired of playing catch up with MS technologies and all the freaking featues they pack into them. I mean: ASP.NET. ASP.NET AJAX VB.NET 3.0, LINQ, F#, C#, J# (being retired), VBScript, VS 2003, VS 2005, VS Team Foundation, Windows Workflow, Windows Communication Foundation and Windows Presentation Foundation. Seriously?
Windows Workflow in particular is extraordinarily huge. If keeping a program in one's head is important (and it is), then it's not going to happen with Windows Workflow. As I get more comfortable knowing what I want to code and how I want to code it, I'm finding myself just wanting to use stuff that gets it done in the path that is the most natural to me.
Silverlight? No, thanks.
