At last year’s TED conference, Tim Berners Lee called for the an open data movement with the free sharing of raw data and all the benefits that would come from that. You can watch the original talk here.
Last month, he gave an update in this six-minute talk. He shows how mashable maps are being produced from the raw data. What I found most interesting was the way information was gathered and shared about the Haiti earthquake. It’s about 4 mins in.
