I am hoping to go to Pubcon in Las Vegas this November. Flights to the US are very cheap from Japan, so it is probably a good time to go if I go back to Australia next year.
It would be great to meet up with anyone who is planning to go.
From their site:
Whether your primary role is in web site marketing, corporate IT development, or as a technology business management, you will find something of value at PubCon (aka: Publishers Conference). It is also designed to be fun and entertaining with ample opportunity for quality networking.
