I post on Facebook so others know what I think. As a business owner then, it's not a stretch to call this a fundamental part of "brand building." Facebook, Twitter, blogging, these are our culture's most contemporary methods for direct brand-building. On the other hand, it's also an interface for brand-bashing. If you've followed some of the Facebook faux pas of late, you'll realize that social media is a two-way street, and sometimes cars come at you on your side of the road!
