Comment: I use pens instead (Score 4, Interesting) 243
As a long-time geek, I carry lots of pens in my shirt pocket. I decided to turn them into business cards.
I had a bunch of nice-looking personalized pens made, with my e-mail address inscribed on them. If someone asks me for my e-mail address, I hand them a pen. I then have to explain that the pen is not to write down my e-mail address, but it has my e-mail address alreay on it, and they can keep the pen. I have handed out more than 100 pens in the last couple of years. People tend to keep them longer than paper business cards because they have utility: you can write with them.
My e-mail address includes my name, and if you search the Web for my e-mail address you get my web site (hosted by the workstation under my desk at home) and my résumé, which includes a picture of me, my telephone number, and my mailing address. That's better than a business card.
