They often lead the way and know how a conversation is going. However, many other people don't think so. Shy people simply don't know how to start or don't have the courage to start. Shyness is feeling insecure about communication and simply being afraid of making a mistake and not having the courage to start a conversation. They feel speechless and breathless when having face-to-face communication due to unpleasant feelings. This leads shy people to talk less than others. However, with the expansion of social networks, such as Facebook or Twitter, the problems related to shyness have been solved. Shy individuals find it difficult to start a conversation, and Facebook and other social networks have provided an easier way that is simply to say "hi." Nervous users don't have to deal with others face to face, they also don't care about expressing feelings. Most social networking services provide a feature that helps users discover friends' personal information such as interests, religion and politics, hobbies. This is an advantage for shy individuals who have more information and ability to carry on conversation with others. Online conversation is now more fluid for shy people. They will no longer be ashamed of themselves for the mistakes they make during online communication, because they can easily fix them while chatting. With online chat services, shy people feel more comfortable. Additionally, a study from “The Influence of Shyness on the Use of Facebook in an Undergraduate Sample” found that normal users spend less time than shy members on Facebook.
