Drew and Kevin have really created something special with the "event" bloggers phenomenon -- it all started at TechEd Dallas and has grown ever since.  With PDC and all the new technology that we are announcing I predict this will be a big hit to see instant community reaction!  I'm very excited to see this inaction.  You should definitely sign up whether or not you are attending, it will be a great way to experience the PDC vicariously through everyone there!
