Study finds most high-comment GitHub repos have zero outside contributor engagement

An analysis of GitHub repositories found that seven repos appeared to comment on 40–80% of their issues, but deeper sampling revealed a starkly different picture. After filtering out pull requests and applying a minimum 30-issue threshold, five of the seven repositories showed a third-party commenter rate of exactly zero across a 25-issue sample. This suggests that most of the commenting activity in these repos comes solely from the issue authors themselves, with no external community participation. The researcher also surveyed 21 similar repositories active since August 2026 and found none that met both a high comment rate and meaningful third-party engagement. The findings indicate that high issue-comment counts can be misleading, often reflecting self-contained notes rather than genuine community conversation.
