From the article:
Exchanging business cards is a rudimentary form of networking (the people, not the server kind). However, to get the most out of the exchange, you need a card that attracts attention and reflects the image or values you want to project.
Unfortunately, OpenOffice.org Writer’s tool for producing business cards does such a poor job of realizing both these goals that it is better avoided. However, if you know where to look, Writer also includes other tools that make designing business cards as easy as possible.
