I don't mention Perlmonks on my resume, because if you mention Perlmonks, should you mention mailinglists and Usenet groups you participate in as well? Mongers memberships? Your CPAN id? My resume is 3 pages, but all I say about Perl is:

Besides having 17 years of experience with Unix, I am very experienced with Perl, and a contributing member of its community. I was a major tech reviewer of [list of books], and a tech reviewer of [list of books].

contributing member of its community covers it all I think. It gives a possible opening in an interview, but it avoids questions like "what are Perlmonks?". Or strange associations. Don't assume a possible employer knows anything about the Perl community, let alone Perlmonks.
