I love business cards. I think of them like calling cards of old. When I meet someone I want to exchange info with, chances are we aren't using the same kind of smart phone so I can try to MMS my info or something but it isn't necessarily going to work. I don't use Outlook or have a Windows OS on mine. If other iPhone users have a particular app I can trade info with them, but all that's so complex. So I went to ooprint.com and got 250 free business cards and put my info on there. Plus, I have one set of cards for personal and one set for professional, since I have separate Twitter accounts and email accounts and so forth. I like the compartmentalization they give me.
