When talking with an artist at Anime North, they'd noticed it seemed they were collecting an awful lot of business cards. By the end of the convention I had to agree – it seemed that a lot more people had business cards, be they for their own business or just personal contact. I certainly left with quite a few of them.
Perhaps it's just me, but I honestly feel people are using business cards a lot more, including for personal contact and for their hobbies. It's to the point where I think we may need a new term for "non-business" business cards.
