Why go? Well, first of all, it’s a good place to meet with your affiliate advertisers, as well as potential advertisers, other publishers, and rub shoulders with the guys who are already making big $$$ in the industry.  The second reason is that if you’re serious about affiliate marketing, you can pick up a few tips and tricks (more than a few actually), and stay ahead of the game.  I learned about myspace and facebook at my first CJU, for example, and how social networking was poised to take over the world.
