Speaking of citizen science, Gale McCullough (PopTech 2010), a former nursery school teacher and old-fashioned naturalist, discovered a whale that had journeyed an unprecedented 6,000 miles from Brazil to Madagascar. The technology she used? Flickr. Through the photo sharing website where people post their “I-went-on-a-whale-watch-trip” photos, she found matching photos of the whales.
