This person should have attended SecondConf in Chicago. They got the name tags just right. So much so, that everyone at the conference mentioned it. Big name and Twitter handle that you could read across the room.
I was thinking that as I read through this post. I have the nametag from that conference hanging right near me, and I kept checking and seeing that it matched every point. It's not magnetic, but it is length-adjustable to avoid the belly problem.
Any linkable images of the nametags? Just curious to see how they look.
