Every now and then, I have a moment of surprise and shock when not only does someone in our government have a bright idea, but they actually implement it. The FCC has started work on a cell-phone version of the emergency alert system.
I remember listening to the old emergency alert broadcasts on the radio, which were a great idea at the time, but now almost no one I know listens to the radio, except for a few that might tune in during the morning commute instead of listening to their CD or iPod. But pretty much everybody has a cell phone these days, and they're always on.
Of course, this now means that every now and then, we'll get a text message that says, "This has been a test of the emergency SMS system. This is only a test. If this had been a real emergency, you would be reading text that is of actual value to you."
