By day I write Python and JavaScript. In the past I have been paid to write C#, Objective-C, C and bash. In my spare time I tinker with Scala, Go, C and Objective-C.

On StackOverflow my questions and answers include C, Python, Scala, C#, Objective-C, Java, VB.NET, PHP, Django, Javascript and Go.

I think it's a good thing to keep a perspective on things, from different languages and different paradigms.
