Chris Wanstrath's blog post, highlighted by @ab5tract, examines GitHub through the perspective of the ethics of commons-based peer production, emphasizing how its features, like the `git blame` function, contribute to this model. The `git blame` tool is discussed as a mechanism that not only identifies the author of a commit but also serves to promote accountability and ethical behavior among participants by highlighting responsibility, thereby reducing the risk of malicious actions. This aligns with the paper's criteria for peer production systems, which require mechanisms to mitigate negative impacts, similar to moderation systems on platforms like Slashdot and Wikipedia. The post suggests that such functionalities are essential for fostering a culture where virtue encourages further virtuous behavior within the community.
