@Bass: Not me. I don't have Silverlight installed because I don't want websites running shaders on my poorly written NVidia drivers.

Sadly though, I do have WebGL because Google Chrome installed it without asking me, I have no intention of ever using it, and it makes my entire system much more vulnerable to russian exploit sites - and hence makes me much more likely to lose my credit card details.

At least if I lost my credit card details to Silverlight I'd have actually chosen to install it.
