Today 250 professionally printed business cards arrived for me. I went for a simple design but the important thing is that it matches my website/portfolio/CV and the contact details are there. I didn't want something overly clever or gimicky – sorry, that's not me.
As you can see, I'm not keen on the whole internet having my mobile number, just yet. If you want it/need it you can ask for it. Otherwise, send me an email. :)
