My school strongly suggested we buy them, and the student bar association took orders. They suggest that we use them for networking in looking for jobs and things like that, since it's a bit more professional to hand someone a business card than scribble your email/phone number on a napkin.
My dissent:MP: I am saddened by the fact that you attended a seminar on business cards.Jacy: Your career services office is wrong. Unemployed people should not have business cards.
