It's true no one cares for the most part. But clients do want maintainability, so a more mainstream language makes your skill-set more attractive. Of course I speak as a freelancer, not from a product perspective.
I picked Python, because:
1. I thought I would give up if the language was too hard.
2. I didn't know what I want to build eventually, and Python seemed to be used everywhere.
Getting into the mindset of spotting problems, defining it's scope and writing code to solve that SPECIFIC scope has been highly useful. It's also something to continually improve at. Good places to start are complaints from friends/family about commonly used software.
