Advances in information technology have resulted in the development of various computer-mediated communication tools of which the Instant messenger (IM) is one of the most prevalent. Instant messaging apps are widely used today for information sharing. The present study ¿Knowledge sharing over instant messaging apps: a study among Kinfra community, Malappuram¿ is based on the importance of instant messaging apps and the authenticity of the information sharing via those apps which helps the users to determine its reliability. The need to conduct a study based on the trustworthiness of the information sharing is desirable and useful for the users. A structured questionnaire is used for collecting data which are personally distributed or sent through mail. The investigator¿s conclusion on whether or not instant messaging has negative effects on real-life social networks is, well, inconclusive. People have varying opinions on the topic, and there is evidence that can demonstrate both the pros and cons of using instant messaging. The safest thing to say is that the effect of online communication depends largely on the personality and habits of the user himself.
