Most people I know in geek life don't use business cards in person any more.<p>I would recommend that you build a simple website in HTML and host it on something like GitHub Pages with a custom domain, and use that as contact info.<p>I also use LinkedIn quite a bit.
Had to get some cards done for pyATL. Did the vista print cards on recycled paper. They’re nice and people do appreciate when I tell them they’re printed on recycled paper. No need to overthink it.<p>One thing that people miss is that the best way to get other people’s business cards is to give them yours first. Great way to gain 1:1 access to a lot of industry folks.
