Xmas cards tell someone you are thinking of them and wishing them well. It is irrelevant whether or not you ever see them. To me that is all the more reason to send. Unless of course you dislike someone and don’t want to send good wishes! I suppose I am eccentric to think a text or email instead of a card is rather insulting.
I did say to DH after a rather frazzled day involving going to the Post Office twice (don't ask!) and going to buy yet more cards, I did say perhaps we should sent electronic ones next year.

I agree, this is why we send them.
