The big brands are quickly learning how to market using the social networking tools of the day. Case in point, a new Facebook application namd Alter Ego that is just plain….well….cool. And you can see the Burn branding all over it, which is a Coca Cola brand. In Alter Ego you can create an alter ego for your Facebook account. Your alter ego has a cooler name than you do, has a cool flat to customize with furniture, and goes out every night with your Facebook friends (or just other Alter Egos). The next day the news item posts in your Facebook account talking about what your alter ego did while out on the town, and with whom. Oh, and did I mention there are pictures from your escapades too? The application is the brainchild of Miami-based interactive agency iChameleonGroup. The new Facebook app is launching today. When it gets wildly popular, just remember you heard it here first.
