It tells me that they're working fast and don't always understand what I'm trying to say the same way that I do. What's even more irritating than a bad headline -- or at least as irritating -- is when they edit and garble the meaning of the text. They often print letters that are close to incomprehensible, certainly incoherent. Yet I send them something that's been carefully thought and carefully written, and they garble it by editing it unnecessarily. (Not that that always happens -- or even often -- and sometimes they make improvements, too.)
