We send approximately 80 cards every year. The number is steady, although names are added and dropped from time to time. We usually receive 60 or so and I think we're on track this year. Some of my friends are habitually late (including two families who generally get around to sending annual newsletters sometime in March).

I used to send my cards very early, but procrastinated this year. We wrote our cards in a marathon session last weekend. Though it's a chore, I wouldn't consider dropping it even though now we can keep in touch through the internet (and I'm now receiving some ecards and emailed newsletters).
