Dreamforce is less than two weeks away and thousands of B2B marketers are preparing to converge in San Francisco for the cloud computing industry event of the year. Last year, we published an infographic showing a brief history of Dreamforce and because it was so well received, we decided to update it for 2012. This infographic contains key historical information on Dreamforce, the hottest B2B marketing people to watch (or, rather, follow) on Twitter, and a few helpful tips to help you prepare for the madness (for starters, think comfy shoes and an unreal mountain of business cards). As you put together your agenda, be sure to check out Marketo’s individual sessions and RSVP to our Masterpieces party on September 18!
