I can't help it, but each time if I see someone advocating Ruby, it's like I heard some Python user. Everything is relative to Perl. But if Perl is the measure, Perl is good enough for me.

Seems Perl is the measure for Perl6 too, just a better Perl by some peoples measure. So, if others find Ruby to be a better Perl by their own measure, it stands to reason they'll use Perl when describing it.

I think Ruby's biggest weakness is that's its RAA (cpan equivelant) isn't as well developed and as standardized as CPAN. I think CPAN remains Perl's big killer-app. Ruby does have mature templating systems, but as you know, everyone who invents a templating system does it differently. It doesn't seem so odd that a particular templating model "X" might not exist in Ruby and someone would rather see a port of model "X" than use one of the "Y" or "Z" models already implemented in Ruby.
