Shiny happy TED and the shadow of suffering

To make up for my cynical anti-TED postings of the last week or two, here is an awesome TED talk from this year's event, about the American prison system's race prejudices. It's also about identity, and the need for TED not just to focus on technology, design, entertainment, and successful happy rich people, but also to recognise suffering, poverty and injustice, and incorporate them into its identity and worldview. Couldn't agree more. The speech is also a masterclass in rhetoric - setting out your stall, focusing on personal stories, challenging the audience but also taking them with you, connecting the end of the speech to the beginning. Brilliant work.
