Christmas cards were always something I looked forward to in the weeks leading up to the holiday. When I was kid, my parents would receive many cards in the mail, some with interesting family photos and/or newsletters.
Not to be Grinch-ish here, but I never quite understood sending out a detailed account of what occurred in your family during the course of the last year. Call me crazy, I can tolerate a few paragraphs about your year, but certainly not two pages of single-spaced type.
I care about what is going on in your life, but not THAT much.
