Business cards

Now that I've moved to Boulder, Colorado, I need to get new business cards.  Worse, I have to get two sets of them, one for my finance column (Finaxyz.com) and one for my main software technology business (Base Technology).

 

I'm thinking about getting a two-sided card since I frequently hand out both cards anyway.

 

I'm also thinking about using one of those online color card services, such as VistaPrint, as opposed to going to Kinko's or another local printer.  Personally I think simple black and white cards look more professional.

 

Is anybody putting their blog URL on their cards?

 

Anybody have any advice or feedback?
