Rex Hammock noticed a peculiar run on gasoline in Nashville, TN this morning. Cars lined up for blocks at some stations.
He quickly put together a Twitter account where people could exchange information about which stations still had gasoline.
Today people buy cellphones without much thought about their overall capabilities. Sometimes a purchase is made as a fashion statement.
However, it's important to realize that a cellphone might be your only access to the Internet during a disaster, crisis, or weird social phenomena (such as Nashville this morning). Choose one with that in mind.
