"The New York Times has reported that Al-Qaeda has designed Foursquare to identify popular locations for bombings!"

"Actually, Brooke, that's been discredited as any kind of real threat, the people that use that site are the people that no one would mind seeing bombed anyway."

Funny and informative at the same time.

On serious topics I like to avoid clouding the message with satire.

The Onion's article is great - just remember that the situation is no joke.
