Aligning with the unique intent of an open source project has helped Evelyn Masso feel more satisfied with her contributions to p5.js, a browser-based creative coding library. She realized that working on p5.js was different from other projects like React due to its accessibility-focused intent and the importance of translating documentation, adding new tutorials, and improving compatibility with screenreaders. To understand the intent of each project, Evelyn suggests asking questions such as "What makes this project unique?", "Why was it started?", and "Who is this project for?" She also emphasizes the importance of setting boundaries and aligning expectations with contributors, including response times to posts on GitHub, and sharing perspectives on intent while allowing space for differing opinions. By doing so, she aims to create a more inclusive and effective open source experience for all contributors.
