I've been skeptical of the utility of Twitter, but one man in Japan found it to be essential at a very unfortunate moment. He was in the restroom of an electronics store in Tokyo when he ran out of toilet paper. So he whipped out his phone and sent this tweet:
Urgent request, toilet paper in Akihabara Yodobashi Camera 3rd floor men's restroom
Twenty minutes later, help arrived. Thank you, Internet.
