At the Vienna.pm TechSocialMeeting yesterday I've given a talk called "Perl in Japan" about the japanese Perl community: who they are, how they work, what they do. It contains impressions I brought back from YAPC::Asia 2008. Too many people don't know anything about asian perl mongers. That's a shame because there are some really interesting developments going on there. I've also briefly talked about Perl in Korea; there seems to be a small but intense community and I hope to find out more.
Here are the slides from the talk: http://www.slideshare.net/hanekomu/perl-in-japan
