Dynamic languages prove themselves immensly powerful at places you least expect them to be. I found this out when I started coding in Ruby some time back and I completely fell in love with Ruby when I started working on the webserver project. For the last 3-4 days I'm seeing reference to Ruby on .NET at many places. Most of the links point to a project in Queensland University of Technology which aims at creating a Ruby compiler on .NET CLR.
Even inside Microsof there are a lot of dynamic language advocate and Microsoft is surely doing something in that space. Proof is here.
