It's not just OK to re-invent the wheel as a writer; it's expected. Fresh ways to make the statement, communicate the idea, win the response.  Sometimes it is simply a means
to convey essential information, at other times a desire to win a shift in opinion
or to motivate readers to action.  Or maybe it's "just" to entertain. 
Whatever the ambition, it pays to be clear about the objective, to
appreciate your audience, and understand the media to hand.
