[link|http://jobs.perl.org/|http://jobs.perl.org/] is a job board for Perl people. The jobs require Perl knowledge, the people interviewing can be expected to aggressively filter out unqualified people aggressively, and it is known as a good way to find decent Perl people.

Factors that make this work. Any Perl person who is "involved in the community" will know about this site. HR drones do not. Most others do not. The remit is fairly focused, keeping the profile low.

Cheers,
Ben
