World Economic Forum at Davos is a ultra exclusive conference that I'd love to be invited to (not even sure "how" one gets invited to Davos, or what it costs - I imagine, people who attend generally don't worry about the cost of attending). Robert Scoble and Jeff Jarvis are going, I've met both bloggers.  According to Jeff Jarvis, Michael Arrington of TechCrunch is joining this year and I know they were trying to get a few more unexpected participants). 

I think, last year was the first time bloggers were invited to attend.

This year, however, it's going one step beyond inviting bloggers - they're inviting everyone, who can record an online video, to post their questions online and the best questions will be shown to the entire attendee list, with a bunch of answers provided:

"…Starting now, they’re also asking you to vote on the responses you like best (as of now, there are 60 to see). They will be shown at the annual meeting of machers in the Swiss Alps, starting January 23, and the machers are suppose to respond back at a YouTube booth at the conference."
