This morning I ordered 100 business cards for myself. My university is printing them and billing my student account. One of my peers just told me about this service. It makes the whole process a lot easier because there are fewer decisions for me to make.
I never think about having business cards until I'm at a conference or something, and then it occurs to me that they might be useful. So, soon I'll have some. Do any of my grad student readers have business cards, or did you when you were a student?
