I'm an ASP.Net (VB.Net) developer professionally.
I've also built a site using Ruby on Rails. In the off chance anyone cares to visit it, hillerenterprises.com is a site I built for my wife's father using RoR.
I've recently been working through the problems on Project Euler (http://projecteuler.net) using Python. I love that site.
I'm now playing around with Common Lisp, too. Land of Lisp was an inspiring read.
