We are keeping the conference small and intimate so you will be able to interact with the speakers and attendees during the day and during the social events. The conference costs $450 right now for two days worth of speakers, breakfasts, lunchs, and a beer and wine tasting. If you are looking for more work, this conference has also drawn the attention of a lot of hiring employers who are looking for developers.
If you are interested in going, I would recommend getting your tickets soon at http://jsconf2009.eventbrite.com as they are selling quickly. For more information or other speakers, check the website at http://www.jsconf2009.com Thank you for your time and hope to see you at JSConf!
