Chicago Tribune: Saturday USPS mail delivery?

Chicago AM Thursday 8 February 2013

Voice of the People, Chicago Tribune

Since the Post Office's founding by Benjamin Franklin 238
years ago (1775) , its backbone has been delivering personal
letters between individuals.  This application was taken over
100% by internet email in 1988.  The Post Office should have
recognized this, and immediately established USPS email.
Once Yahoo and Gmail got started, the USPS lost its number
one product.
