As someone who strongly dislikes complicated languages, it's obvious to me that it's a matter of personal preference; personal aesthetics, if you like. If the choice is between complexity in the language and elsewhere, often I'd rather it be elsewhere. But while that preference is entirely subjective, what isn't subjective is the distribution of that preference among programmers. I think that we can say with as much certainty as we can about these things that the answer is clear: the vast majority of programmers prefer simpler languages. So much so that while language simplicity is by no means a sufficient condition for high popularity, it seems that it's a necessary one.
But I'll go further. My gut feeling, which is by no means even remotely scientific, is that those who prefer simpler languages outnumber those who prefer complicated ones 9:1. Moreover, my feeling is that the ratio is higher at the low end of programmer capability than at the higher end — and it makes sense, as more capable programmers can handle more complexity, so some — still a minority, but a larger one —prefer moving more of it to the language.
