Enjoyed meeting Melissa Darragh at TEDxHouston happy hour last night. She has set me to thinking about the networking model again, as did Kelsey Ruger when he as pushing this thread in Quora. 

You can look at a thousand ice-breaking tools and structured networking tools, but the first requirement is that you have someone who wants things to be different. Most people just don't care. An exchange of business cards still works good enough for them. 

I wonder if there is a way that we can change things at an attendee level, instead of expecting the organizers to change it up. Durwin Sharp has a little booklet called a Passport, full of questions you can ask someone to fill in, but it takes a big bite of time and commitment to use. Maybe we can develop something more casual. Suggestions welcome.
