If I said nobody whatsoever under 30 codes Perl, you would count in my poll. I said nobody I know. I realize there are some of you, but you must know that there aren't many of you, right?
Most people I know that code Perl are in the 25-30 range, and I consider myself pretty widely connected in the community. Why do you care about age, anyway... it's a programming language, not a boy band.
Ok, here's your premise: Perl is dying.
And here's your argument: I don't know anyone below thirty in Atlanta that uses it.
Don't you actually see where your logic slipped? Sure, CPAN having doubled their upload rates last year doesn't mean anything, but the few young acquaintances of your personal social circle really add up to your statistically proved statement.
Do I know young Perl devs, personally? No, but that is also true for every other language (I don't know any other programmer personally, odd no?). But what would that prove anyway? It's too small of a sample size to reach any conclusion.
And, as jrockway said, there are lots of young Perl coders out there, they just don't happen to be my neighbors.
