I thought DeFrag on the whole was worthwhile - although I would have preferred much more time to brainstorm (forced to brainstorm, I guess) with attendees. I got the sense that the panel participants were not necessarily a whole lot smarter than the attendees in the audience. I was also bothered by the nonstop microblogging. I mean, guilty, as I got sucked into it (I hadn’t really microbloged before, so I was playing around with it) .. but come on - you come all the way to Denver to listen and pay attention - not to stare are your laptop. I think old bad habits die hard, and microblogging is just a worsening of the whole ADD problem with social technologies.
