Ellen DeGeneres has a new crusade. The popular comic and TV host wants you to buy stamps that support dogs and cats, and to use the post office to help save Saturday delivery. Maybe, Ellen DeGeneres can make a difference for a few dogs and cats. But the perpetual problems that the U.S. Postal Service finds itself in seem without end.

While Ebay and other auction sites mean huge transfers of merchandise, the U.S. Postal service finds itself in competition with UPS, FEDEX and other delivery services. And letter volume is down as well, thanks largely to the use of Emails and FAX machines.

Can Ellen really make a difference? Well, it's a little bit like the old story: A man rescues a star fish by tossing it back into the ocean. He didn't save every star fish. But, he made a difference for that one.
