With the advent of knowledge intensive firms, organizations have started viewing knowledge as an important resource for their competitive advantage. In order to make knowledge as a resource, organizations have implemented knowledge management initiatives in order to codify, share and create knowledge. Recently, newer forms of Information and Communication Technologies (ICT) such as web 2.0 (also known as social software) are facilitating user participation, communication, interaction and collaboration on the web. This article analyzes and discusses the adoption of social software in Indian based software consultancy firms by taking into account the individual knowledge worker’s perception according to social dilemma theory and Hofstede’s framework on national cultures. Based on the analysis of data, we have found that even though software consultancy firms are deploying these tools, however the use of these tools is rather low due to both personal and organizational factors.
