Abstract

Understanding motivations of contributors for participating in community question and answer platforms is crucial for sustaining knowledge-sharing ecosystem, which is necessary to advance the discipline while also ensuring its longevity. This is particularly necessary in the age of LLMs, where data from such portals are used to train these models. Limited insights exist regarding how motivations of contributors vary across different national cultures. This research investigates Stack Overflow contributor motivations, analysing regional differences and relations to platform activity. We combined qualitative content analysis of Stack Overflow profiles with quantitative linguistic analysis of data from the United States, China, and Russia. Using deductive content analysis, we identified 17 motivational categories. We applied correlation analysis to identify associations between stated motivations and platform activities. Contributors are primarily motivated by advertising opportunities and altruistic problem solving desires. American contributors demonstrated stronger self promotional behaviours while Chinese contributors exhibited greater learning oriented engagement. Our correlation analysis showed that those with more detailed profiles tend to engage in advertising and social activities, while learning oriented users maintain minimal self presentation. Understanding these variations can inform strategies for enhancing cross cultural participation in software engineering.
