A philatelist's nightmare.

Make-it-yourself stamps. There's a suggestion that the USPS adopt a plan already in use by the Canadian postal service whereby you can send in a picture and have the USPS turn it into a stamp. It would cost more than a regular stamp - presumably, enough more that the USPS would make a tidy profit on the deal (Canada charges $25 for 25 48-cent stamps) - and couldn't have a copyrighted image. This would have to be tough on stamp collectors, who would have to limit themselves to collecting "official" releases instead of "authorized" stamps. But Hey! A new outlet for my photographs, in addition to Christmas cards.
