But sometimes I like to be able to hide my identity when checking out / chatting with the competition ;)
Which is exactly the reason I wish conferences would put the name on both sides :-) I actually find it more with financial analysts than competitors. Many deliberately turn their badges around in the hopes of getting some tidbit from someone in a show floor booth who isn't on their guard.
But this is Facebook we're talking about ;)
Hanging these from the corner means that it's much less likely for them to flip, so you don't need the name on both sides.
