According to SMM World:
"We give marketers like you the ability to get all the information you need in one place, personally connect with the top experts in the world, form lifetime relationships that’ll help you year-round, and gain the confidence you need to succeed in your job."

This is a cool event, but I believe it's better suited for bloggers than companies
