Firstly, I have only been to one and had a great time meeting people and learning tons in the process.

I don't know if the conferences already touch this subject but I think it would be beneficial to look at certain projects and study, question and talk about the built projects from the infancy to completion. Enlighten others about the setbacks and accomplishments, how subs if any were involved in the project and how they were beneficial or detrimental, in short what was learned. All for the goal of helping others recognize different aspects of the project that would not have been known unless they were there or someone shares and hopefully helping to promote good building.

Thanks
