As some say (me included), it’s nice to give people something of value just the moment you first meet. It binds. And what is of more value than an insightful point delivered in a funny way? Plus it doesn’t cost you much and has potential to change the world (a wee bit, but still).
So why not add some value to the usual biz-card exchange? Say, in form of couple of valuable words on the back side of a card? And I bet you can also make it fun to read. In order to boost up the fun factor I used couple of doodles by Hugh MacLeod.
If you want to print each card with a unique picture on the back, moo.com is the place.
