I realize the title of this post sounds like something out of The Onion, but it's actual news.
Scientists in Western Australia, where there have been several deaths from shark attacks in the last two years, have tagged 320 sharks to monitor their movements. When a shark swims near a beach, it will trigger an alert and then the size, breed, and location of the shark will be posted on Surf Life Saving WA's Twitter page.
It's a fast messaging system and perhaps the smartest use of Twitter I've heard so far. (And, yes, people kill 100 million sharks every year--versus the 12 people last year killed by sharks, so perhaps we should instead be warning sharks of our location.)
