Actually, where I work, we use Perl almost exclusively. I don't know a single person who I would consider a "noisy evangelist" - we just quietly get stuff done.
There is a Steve Yeggie quote, though its not necessarily praise for Perl, which always pops to mind when people have a rant about Perl:
'As I've done for a great many other programming languages, I've bashed on Perl's technical weaknesses at length in the past. To my continued amazement, the Perl folks are the only ones who never get upset. They just say "Haha, yeah, boy, you're right, it sure is ugly. Heh. Yeah, so, um, anyway, I'm going to get back to work now..." It's awesome. I've gained so much respect for them. It's almost enough to make me go back to programming in Perl. Well almost.'
