It works. It's fun. It's yellow (and black).
The talented people at BzzAgent are working hard to bzz the new Purple Cow book. As I've mentioned before, this is a secret organization that creates organized word of mouth with an army of volunteers.
If you click on the BzzAgent: Purple Cow Campaign and they accept you, you get a free copy of the hardcover book, a very cool packet of stuff (it blew me away) and a chance to earn unique awards.
They've got thousands of agents around the country, and at my request, BzzAgent is holding 100 more slots for Purple Cow fans to join them. Not much time, though.
