But the main issue is, the writer doesn't really gives any advice as to when to use Perl, and what are the preferred usage of it other than "Perl has these features, it's not C, I prefer rails, and don't write bad code".
Or, in other words, "Hi, I'm a puff piece intended to fill a page or two."
BTW, thanks for the pointer to use.perl.org; I hadn't encountered it before.
