One of the interesting things about the internet is the opportunity if offers people to present themselves in a variety of different ways. You can alter your style of being just slightly or indulge in wild experiments with your identity by changing your age, history, personality, physical appearance, even your gender. The username you choose, the details you do or don't indicate about yourself, the information presented on your personal web page, the persona or avatar you assume in an online community - all are important aspects of how people manage their identity in cyberspace.
Identity is a very complex aspect of human nature.
The multiple aspects of one's identity may be dissociated, enhanced, or integrated online. A single person's identity embodies multiplicity. You possess many sectors within your personality and play numerous roles in your life - such as child, parent, student, employee, neighbor, friend. Cyberspace offers a niche for each of these specific facets of selfhood. We don't have to present ourselves in toto - how we look, talk, move, our history, thoughts, feelings, and personality, all in one big package.
