Totally agree that sending cards to people you see all the time, eg work colleagues is bonkers. We only send cards that go in the post box. I would, however, find it hard to stop doing this as 80% are to relatives/friends, all older than us, who do not live nearby and do not see our (young) DC and we do send them a picture with the card. I do this because I think an older/elderly person quite likes this and it's not too much effort on my part. Am I wrong? (We could stop the 20% though).
