🔹 Invited Lecture Title

Social Media Reactions to Open Source Promotions: AI-Powered GitHub Projects on Hacker News (Accepted for publication at ICSME ’25)

🔹 Abstract

Social media platforms have become more influential than traditional news sources, shaping public discourse and accelerating the spread of information. With the rapid advancement of artificial intelligence (AI), open-source software (OSS) projects can leverage these platforms to gain visibility and attract contributors. In this study, we investigate the relationship between Hacker News, a social news site focused on computer science and entrepreneurship, and the extent to which it influences developer activity on the promoted GitHub AI projects. We analyzed 2,195 Hacker News (HN) stories and their corresponding comments over a two-year period. Our findings reveal that at least 19% of AI developers promoted their GitHub projects on Hacker News, often receiving positive engagement from the community. By tracking activity on the associated 1,814 GitHub repositories after they were shared on Hacker News, we observed a significant increase in forks, stars, and contributors. These results suggest that Hacker News serves as a viable platform for AI-powered OSS projects, with the potential to gain attention, foster community engagement, and accelerate software development.
