I bet I have used languages with the same frequency as this kind of question comes up on
Seriously, it's all just syntax, convention, and architecture, so I don't bother to track. Off the top of my head, I'm up to 30+ "languages" in 30+ years. Throw in media (yes, starting with punch cards), then it gets worse.
I think a more relevant question is how often does one advance their architecture, paradigms, and most importantly debugging skills. Anyone can write a program that compiles and does something. Building something that is understandable, useful, usable, and maintainable, now that's a discussion.
