Dumb ways to die
Dumb ways to die is a successful viral public safety campaign. Some nice coverage on ABC with the people behind it.
Update: Econsultancy have coverage now too.
I woke up last Monday after a weekend of not much social media, and while checking my networks on the train to work I discovered that about 6m people had beaten me to watching Dumb Ways to Die, which could also be re-named as “the little train safety campaign that could”.
