Is this the year of eCards in UK?
According to The Time, "Royal Mail’s chief executive has painted a bleak picture of the industry’s future — and warned that the current strife could result in people deciding that this was the year they would stop sending Christmas cards."
I don't think people in UK will stop sending paper Christmas cards. The strike will definitely have some effect, but there are still many weeks away from Christmas. There are enough people who believe that paper cards are a special part of their holiday. For many people, paper Christmas cards are often set out on the mantel or some other conspicuous place. Try to do that with eCards.
Maybe we should add the functionality for the recipients to print out their ecards so they can put the "cards" on the mantel-:)
