Python: 84.6%
C: 54.0%
C++: 48.2%
Java: 48.2%
JavaScript: 47.6%
...
Ruby: 21.0%
Why is Python so far ahead of everything else? Why is Ruby, which is all about programmer happiness so far down?
It seems people actually like JavaScript. Wait, people do actually like C++?!?
Also if you take a look at Go by age, for example, it goes from 53.6% (35-44) up to 67.8% (45-54) and back down to 7.6% (55+). I don't see a reason for such a huge preference variation. There's also a few 0.0% with 55+ years.
It seems there weren't enough answers for this to be anywhere near conclusive.
