Brands like VW and Bud Light are savvy to this. They are integrating and leveraging the power of Facebook into their marketing. Notice how they use custom tabs on their pages to present fully controlled messaging. Importantly, brands can leverage the data power of FBML within this controlled presence.

Try the VW "Analyze Me" tool and you might be shocked at what it immediately knows about you.
While these pages aren't replacing their brand.com sites, they are at the forefront in connecting with consumers online; and serve as an important touch point and traffic driver. If your brand targets consumers and isn't doing this kind of social media marketing, you should be considering it now.
I love this shift! This continuum in the evolution of communications is what makes my career invigorating. I love learning the lay of the land in emerging media; and then applying classic business and marketing principles to them.
I am fortunate enough to work with some amazing visionary clients and fantastic people at BOSSdev to create compelling Facebook solutions. I'm tipping my hat towards you, Mr. K. Alan Robbins.
