This is a liveblog of Ethan Zuckerman's keynote at Links 2013. His slides are available online.
Ethan opens by saying that his stock and trade is "the unusual connection." He starts talking about the Harvard Peabody Museum of Archaeology and Ethnology. The museum hasn't changed since it's early collector mentality. The labels actually list the white dude who collected the items rather than their creator. It's still a colonial approach to museums.
He shows a "rebellib" or "stick chart / shell chart" which is a map from the Marshall Islands with shells representing the islands and curved and diagonal lines representing ocean swells. Since the Marshall Islands are scattered across 500-600km. A Marshall Islander around 1900 is going to be in their boat and traveling between the atolls without seeing them over the horizon. You must travel dozens or more kilometers at a time between them. And when you miss the next atoll you die. And bad things happen evolutionarily if you die on the way to the next atoll. There is a need for inter-island "booty calls" to produce the diversity necessary to sustain a population.
Contemporary scientists have gone back and found that these rebbelib are incredibly accurate. And if you check Google Maps, you realize this is an area of the Earth that we have not sufficiently mapped. Google is a decent proxy for interest in an area since the best resolution is based on demand: people's willingness to pay for high resolution images without clouds.
