Here's my card

So I've finally broken down and ordered business cards. I'm rather sheepish about it. Someone in the church was kind enough to put it together and send the file off to the printer. I've been asked several times if I have one- and been able to say no. No longer. There has got to be some sort of business card etiquette that I've been missing out on for years now. I get handed cards often enough but rarely at my request. I'm sure there is some article out there detailing the business card exchange ritual. If you know of one- point me to it- or write one and send it to me. There has got to be some protocol that distinguishes you from the cold call timeshare salesman that just happens to be in the area and wanted to drop his card off. Maybe not- oh well, here's my card.
