1. Not enough people asking great questions. 2. The answers to questions was only vocal, with no presentation or material to back it up.
The first was easily solved by seeding a few question in the public to get things moving. However the number 2 was a major problem. Many people were not able to connect to the answers/discussions.
I would love to know if you are able to solve the 2nd problem.
Thought I would share my experience.
