Online, barriers that might stand in the way of a potential relationship such as physical attractiveness, social anxiety and stuttering do not exist. Whereas those could hinder an individual in face-to-face encounters, an Internet interaction negates this and allows the individual freedom. Research has shown that stigmas such as these can make a large impact on first impressions in face-to-face meeting, and this does not apply with an online relationship. Furthermore, as the internet has become a worldwide phenomenon, many people can interact with others around the world, or find someone who fits their radar or their type, if there is no one who they find physically or emotionally attractive in their own area. The internet allows for interaction of many different people so there is greater chance of finding someone more attractive. The Internet "enhances face-to-face and telephone communication as network members become more aware of each others' needs and stimulate their relationships through more frequent contact".
