Currently, with First Class mail taking several days, there is no incentive to pay the extra premium over Second Class, so the impending increase in cost for First Class Stamps means that the Post Office,instead of getting more money in their coffers, will actually get less, and may yet go the way of the Dodo.
Perhaps reducing the cost of First Class stamps would actually increase the takeup and so the profits of the Post Office?
Is it time to set up a social network of postal delivery, along the lines of what Fidonet was before the widespread availability of T'Internet?
