Given its importance to the Perl developer community, the CPAN both shapes and is shaped by Perl's culture. Its "self-appointed master librarian", Jarkko Hietaniemi, often takes part in the April Fools' Day jokes; on 1 April 2002 the site was temporarily named to CJAN, where the "J" stood for "Java". In 2003, the www.cpan.org domain name was redirected to Matt's Script Archive, a site infamous in the Perl community for having badly written code.[17][18][19]
