I've been primarily a C# programmer for the majority of my career, with probably equal parts dabbling in Ruby, PHP, Javascript, Sql (large sprawling analytics framework sql), and a bit of R. When I switched to Ruby dev-work though, my tools changed. I found myself writing a lot more scripts for things which I previously would have made a C# console app for, mostly because osx/linux make it a lot easier. Soon I started writing a little Python, and found I was just plain productive (things that might have taken me many hours would take minutes), and now it's becoming a primary language for me. I'm not sure I'd use it for the majority of my work, but it's probably my #2 language tool.
