I'd say No ... for the very reasons that have allready been expressed (and will likely be echoed by many more).
I would probably agree however that having a "Parrot" Section might be usefull in the not too distant future. While Parrot will be a big part of the Perl 6 Implimentatin, people with questions about the "Perl Language" will not neccessarily (all) care about "Parrot Language" questions.
(Part of me thinks that it shouldn't matter -- that PerlMonks doesn't need a Parrot section anymore then "C++Monks" needs a "MIPS" section. But the difference is that C++ can be compiled down to a wide variety of machine langauges, where as Perl6 will only ever be compiled down to Parrot, so the communities are going to be a little more tightly bound.)
