Abstract
Stack Overflow offers valuable knowledge for software developers, but studies suggest digital information tends to cluster geographically, limiting access to necessary knowledge for innovation. This study explores posts of top contributors on Stack Overflow across the United States, Brazil, India, Egypt, the United Kingdom, and Australia. We analyse platform activities, conduct social network analysis, employ topic modelling paired with thematic analysis, before dissecting their knowledge sharing patterns via directed content analysis. Results indicate that cultural factors, entrepreneurial activities, tech ecosystem maturity, as well as workforce diversity in a region were found to shape how top contributors contribute. For instance, individualistic users communicate directly whilst collectivistic users prefer subtle communication and socio-emotional cues. Moreover, top contributors in nascent technology ecosystems were more likely to discuss fundamental concepts, while those in mature ecosystems focus on specialised niches. This study sheds light on how diversity in human aspects may influence the dynamics of CQA settings, where future researchers can explicate the extent of which latent contextual factors affect user contributions and community structure.
