Does anyone have any experience with the BlogWorld conference?

I just got an e-mail inviting me to take advantage of early bird registration for the 2010 BlogWorld & New Media Expo and Conference taking place this October in Las Vegas.  Since I am always eager to have an excuse to go to Vegas and since I am also eager to figure out a way to take my law blogging to another level (whatever that means), I am thinking seriously about trying to make it to this event.

I am a bit concerned, however, that this BlogWorld event may be more geared to techies and others more interested in marketing than in content creation and dissemination.  Consequently, I am posting here (and in some other blog locales) this bleg for information and feedback on the BlogWorld experience.  Relatedly, I filled out a form to offer to be a speaker at the BlogWorld event (which would make registration free and likely could have other benefits), and I would love to hear from anyone as to whether trying to speak at this event sounds like a sensible idea.
