Hello Everyone
Reading some of your years experience, I feel like a toddler in the game :).
I have been a Site Administrator for my company for the past 4ish years. I have always done public speaking for my team and company for things like training and awareness. TED Talks - wow - what a benchmark - but if i could, I would talk about Adoption and Change Management. I think we there is still a big disconnection with End Users and Technology Teams.
My own quote: Be the change you wish to see in the world, but remember, everyone does not accept change at the same pace. - Robin S
