We can easily purchase anything we want with a few simple clicks and it will directly deliver to you home. Like Eric Stoller says in the video, “your body of work your portfolio your blog your tweets everything that you do on the web kind of represents your digital identity”[1] Digital identity represents one’s behaviours, habits, personal interests. Even we can figure out one’s way of doing things by looking at the comment he/she give to others. Different from physical identity, digital identity involves a wider range of areas, which describing a person more thorough and unique.

Since social media can share one’s feelings, religion and personal values. Personal and professional use of social media can be different.  As professional use of the platform, social media offers a chance to connect with clients on a  personal level and maintain a brand across all marketing channels. The more we post on social platforms, the more public exposure we get. However, it not always bring positive effects. people might be judged from other users with different backgrounds.
