Why does PerlMonks work?
Perlmonks and the community it created is loved because Perl is also loved. Perl's flexible and eclectic style make it easier and even fun to work with, yet Perl isn't a very popular language(compared to C, C++, Java...). This makes a more unique and closer crowd to move towards it.
And besides, with a name like PerlMonks, you know it's for the more hardcore perl programmers. People go to Usenet first because they're not interested in Perl enough to try somewhere else.
