Vincent, Nicholas, Isaac Johnson, and Brent Hecht. "Examining Wikipedia with a broader lens: Quantifying the value of Wikipedia's relationships with other large-scale online communities." Proceedings of the 2018 CHI Conference on Human Factors in Computing Systems. 2018.

This research paper explores the relationship between Wikipedia and its broader online ecosystem, particularly focusing on the interactions with large-scale online communities like Stack Overflow and Reddit. While previous studies have mostly examined Wikipedia in isolation, this work extends the understanding of Wikipedia's role within a larger network of internet platforms. It reveals that Wikipedia significantly contributes to the value of Stack Overflow and Reddit by enhancing visitation, engagement, and even revenue generation for these platforms. However, the relationship appears to be unidirectional, as there is little evidence to suggest that Stack Overflow and Reddit provide reciprocal benefits to Wikipedia. These findings underscore the importance of recognizing Wikipedia's contributions beyond its own domain and highlight the vital role that volunteer-created content on Wikipedia plays in enriching other websites.
