John,
>I'd like to see sessions where attendence was limited to 20 people. Everyone brings a laptop and the presenter leads everyone through the topic
hands on with the last 20 minutes or so instructor-led experimentation with the topic.
That's an excellent point -- I don't think I've ever been in a session like that, although the Double Impact classes have that small intimate feel to them, but don't have the interactive nature that you described.
