In a matter of hours, at 9 a.m. ET Tuesday, about 240 Bridge Worldwide employees will launch a social-media marketing experiment to support the launch of our new book, The Next Evolution of Marketing: Connect with Your Customers by Marketing with Meaning. I’m excited about the launch, and can’t wait to see what comes out of the groups’ work—and I look forward to readers’ participation and feedback.

The book officially launched on Friday, October 2, and it got off to a great start. That morning Advertising Age published an outstanding book review by Pete Blackshaw. I could not have asked for a better and compelling review of the book, and sure enough the sales lift-off was immediate. On Amazon.com, the book rose to the #1,200 seller across all books, and shot up to #2 in the Advertising category, just under The Tipping Point. McGraw-Hill emailed me soon after to let me know that they are already getting ready for a second printing. Thanks to all of you for helping me along the way and for your early book orders.

Tomorrow morning our entire company is going to try to generate some more buzz around the book by engaging in an exercise modeled after P&G’s successful “Hack Night” from back in March 2009. You might recall that the company brought together a couple hundred senior-level marketers and external digital experts for an evening to compete on teams, using social-media tools to sell the most Tide T-shirts in support of its “Loads of Hope” cause marketing program. I got to attend that event and saw it not only raise a lot of money in a few hours, but also get people to learn by working together and experimenting.

A few months ago, our President, Jay Woffington, asked me if we might do our own company-wide “Hack Night” in support of the book launch. His goal was to not only juice book sales, but to give all of our people a chance to further improve their digital sensibility by rolling up our sleeves and working together. This conversation spawned a project and a team and tomorrow’s event.

Here’s how it will work: The goal of the competition is to get as many people as possible to download the free chapter of the book.  We decided to do this because the free chapter itself is Marketing with Meaning, and it is much easier to track chapter downloads than actual book sales. We have split up the company into teams, and assigned each team a specific medium to use to market the free chapter: Facebook, Google, Twitter, LinkedIn, WPP resources, and this blog and community. The teams first met a little more than a week ago to start planning and preparing, and tomorrow at 9 a.m. they will begin their activities in earnest. We will have them each in separate War Rooms, with a live monitor feeding in the total downloads of each team. Everyone will stop working at 1 p.m. so we can go to have some fun at our annual company offsite, where we will announce the winner of the contest and present a few other awards.

Already people to seem to be having fun and are learning a lot. I don’t know much about what they have planned, though. A few teams have asked me mysterious questions, and one team dragged me into a room to film something before I left on a trip last week. “Winning” is one of the key words of our agency’s equity, so I’m sure the competition will be hot and heavy.

My only fear for the day is that the competition will drive people to do things that end up angering our carefully crafted audience. During the P&G Hack Night, one of my friends, Kevin Doohan, who knows several of the participants, wrote about how the contest felt like spamming. I have tried to reduce this risk by providing a coaching brief on how to approach people, as well as how to ask for forgiveness when you make a mistake. But I am sure that some of you might find tomorrow’s event annoying. I apologize in advance and hope that you see that our hearts are in the right place.

Although I am the author of this book and the most public voice of “Marketing with Meaning” I really believe that I am just one of many members of what can be an important movement. This idea has been driven by nearly everyone at Bridge Worldwide, readers of this blog have been incredibly supportive during the past 18 months, and now we have new tools such as our community to bring others into the cause. I am excited that our experiment tomorrow might give many more people exposure to what we’re trying to do together, and give more people the chance to be a part of driving a better future for marketing and society.
