It makes sense to refer to dates in the past few years as oh-[single digit], as in, "I graduated in oh-four and bought a house in oh-five."  Since we're in oh-nine right now, what will happen next year?  Will we of the future start referring to dates using four digits (two thousand ten)?  Or will we finally start doing what our forefathers predicted and call it twenty-ten?  Or even better, will we come up with some stupid slang thing that eventually becomes accepted as common language, like oh-ten?  Oh the suspense! #technology
