It was troubling to hear one person after another lecture about learning more about how people learn whlle violating most of the principles we already know. Aside from the Push format, problems included no hashtag, no Tweeting, no backchannel, no power outlets, inoperable wi-fi (for me, at least), slow wi-fi at the podium cut several presentations short, weak visuals overall, and no encouragement to network online (although many probably already know one another). I don’t know how someone as astute at Peter Norvig could sit through an entire day of this stuff.
