I led a session during the unconference day titled TransitCamp and Open Source Government. It was my first time presenting such a thing, and definitely a learning experience: - good idea to ask audience how much they know about the topic at the start - plan for at least 10 minutes of questions (probably more at unconferences) - work on being a calm and collected speaker
Matt Mullenweg was an excellent keynote speaker. However, I must call bullshit on his suggestion that police can make any meaningful difference containing spam in open systems.
CBC is experimenting with crowd-sourcing Citizen Journalism, at least in Vancouver. I am planning to send them some story pitches, and you can too. This could be an awesome opportunity to open up our media. Hopefully I'll write more about this in the future.
Building a Better Conference Badge is a good read for all organizers. The NV nametags definitely need a redesign. Space for user-tagging is a good idea, but you need to tell people to do it when you give them out.
