There is an organized effort, by the Perl volunteer marketers, to attend non-Perl events and communicate about the all new things happening in the otherwise insulated Perl word. I wish this effort all the best, and I hope that The Perl Foundation will find a way to support it. To enforce the effect I would like to see also the symmetric and complementary action of inviting non-Perlers to our conferences. I am sure that is already happening to some extent - but personally I have not yet seen it - so I conclude that this extent is not enough.
Whom, from non-Perl speakers, would you like to hear at your next Perl conference?
