I've noticed a small but real trend when I travel - non-business business cards.

Sitting at lounge at ATL on a long layover, got talking a lovely couple from upper NY state. When we parted, we're doing the usual "hey, if you're ever in my neck of the woods...' bit. I'm taking out a notepad to write my name/email when the wife handed me a non-business business card. Had their names, photos, email, telephone number.

I've also been given non-business cards by folks from Australia, several places in southeast Asia, and the UK.
