Out with the old; in with the new. It's a common saying at the start of the New Year. In the postal world, however, some old things go out at the end of the year, only to return again in the New Year, like postal reform.
And, of course, some things never go away completely, which is a good thing. For example, we continue to get mail delivery to our doors at least 6 days a week no matter what is happening with the U.S. Postal Service's financial condition.
