We write to communicate. And to communicate well, we must speak the same language as our readers.
Yet too many people who make their livings as writers insist on communicating in a way that excludes. Sports metaphors, pop-culture references and clichés all require that your reader be just like you -- interested in the same things and coming from the same place.
That's a mistake born of laziness and cultural bigotry -- two things that journalists must avoid if they are to learn to write well.
There's an interesting piece on the Poynter site about just this subject.
Take a look.
And take a look at what fellow journalism blogger Doug Shaw has to say.
