As the Internet has grown and developed, sending cards has declined. My guess is that most cards sent today are from "older people". Young people do e-cards if any at all. My great memory (I'm 75) is receiving cards in the 1960's when I was growing up, from people all over the USA - from those that served with my dad in France in WWII. EVERY card had a hand-written note (or even a long letter!) with all the news that happened since their annual WWII reunion that his outfit held every June. The cards were beautiful, and the notes were great.
