The Microsoft site gives you a breakdown into using the web as a marketing tool. I think that this revolves around identity as for example as a designer, you need to network yourself and get your identity out there to the world. The web allows this to happen quickly and cheaply. Social sites such as Facebook and Twitter are commonly used in todays world to advertise for free, allowing information to spread across the world rapidly. This goes back to previous identity articles on how much and how little information you choose to post online, as being selective can help how you are viewed.
