I have stopped giving out or leaving a Biz card. I have now even omitted my address from the card for fear (I would be tracked down and stalked forever) if a deal went south. People are crazy when we talk about their property. Giving out a card with a phone # and email address is an EZ way for anyone that doesn't like you to haunt you. No More Biz Cards.
But, yes Surf Cat, it was great to hand out cards to everybody 1988-2007. Then, only a select few (Atty-CPA etc.) could send you Biz. WE cannot "market" ourselves to the general public anymore. Who took that away?, (other than Cuomo).
