でぶこんふ / デブコンフ

Kenshi Muto discusses potential costs for having a DebConf in Japan, as do other people on a mailing list where it isn't on-topic. I am under the impression that I can get a plane ticket to NRT more cheaply by an order of magnitude than a flight to Helsinki. This is probably because I know tons of people who want to go to Japan and none who want to go to Finland.
