Who should I follow to learn about open-source software?

If you want to actually understand open-source software - not just hear about GitHub projects - I’d follow a mix of maintainers, ecosystem leaders, and organizations.

People worth following

• Linus Torvalds - Linux and Git. Follow for pragmatic engineering and a window into how a massive open-source project is maintained. Leadership | Linux Foundation
• Greg Kroah-Hartman - Excellent if you want to understand how serious open-source maintenance works: patches, review, releases, and kernel development. Leadership | Linux Foundation
• Chris Aniszczyk - Particularly good for learning about open-source communities, developer relations, infrastructure, and how projects scale. Leadership | Linux Foundation
• Nithya Ruff - Follow if you're interested in the business, governance, licensing, and sustainability side of OSS. Leadership | Linux Foundation
• Evan You - Especially useful for seeing what independent open-source project development and funding look like.

Organizations/accounts

• Linux Foundation - Probably the single best ecosystem to follow if you're interested in Linux, Kubernetes, AI infrastructure, networking, security, and OSS governance. Leadership | Linux Foundation
• Cloud Native Computing Foundation (CNCF) - Great for Kubernetes, containers, cloud infrastructure, observability, and modern distributed systems. foundation/charter.md at main · cncf/foundation · GitHub
• Open Source Initiative (OSI) - Follow for licensing and the broader definition/history of open source.
• Open Source Security Foundation (OpenSSF) - Worth following if you're interested in software supply-chain security.

My suggested starting lineup

If you don't want to follow 50 accounts, start with Linus Torvalds + Greg Kroah-Hartman + Chris Aniszczyk + Nithya Ruff + CNCF + Linux Foundation.

And don't just consume their posts: watch what projects they work on, read the GitHub issues/PRs, and occasionally read a maintainer discussion. That's where you start learning how open source actually works.

If you tell me whether you're more interested in AI, web development, Linux, cybersecurity, or contributing to OSS, I can give you a much more targeted list of 10–15 people to follow.

To learn about open-source software (OSS), following the right platforms, organizations, and thought leaders will give you a mix of practical contribution guides, industry insights, and community culture.

Key Organizations & Foundations

• The Linux Foundation: The premier hub for open-source development, hosting major projects like Linux, Kubernetes, and Node.js. They offer great beginner guides and professional training courses. A Beginner's Guide to Open Source Software Development (LFD102)

• GitHub (GitHub Education & The GitHub Blog): Beyond hosting code, GitHub provides comprehensive resources like Open Source Guides (opensource.guide), which cover everything from how to contribute to licensing and building communities. Open Source Guides | Learn how to launch and grow your project.

• OpenSauced: A platform and community focused on open-source intelligence, analytics, and helping developers find beginner-friendly projects to jumpstart their contributions.

Podcasts & Newsletters

• The ReadME Podcast (by GitHub): Features behind-the-scenes stories of major open-source projects, maintainers, and developers shaping the software ecosystem. Tools Intro to Open Source - GitHub Education

• Changelog Podcast: One of the longest-running podcasts dedicated exclusively to open-source software, covering new projects, maintainer challenges, and tech culture.

• OSPO (Open Source Program Office) Blogs: Many tech giants and universities (like Syracuse or Bloomberg) have OSPOs that publish open-source best practices, compliance tips, and case studies.

Core Communities to Follow Online

• DEV Community (#opensource tag): A collaborative developer network where engineers regularly share step-by-step walkthroughs for making your first pull request.

• Reddit (r/openingsource or r/learnprogramming): Great places to read about community experiences, ask questions, and find curated lists of "good first issues". A step-by-step for doing your first open source contribution ... - Reddit

Are you looking to learn open-source from the perspective of using and contributing code , or are you more interested in starting and maintaining your own project?

⚠️ Risks & Considerations

• Over-reliance on individuals: Some contributors may shift focus or reduce activity, so balance by following organizations.

• Corporate influence: Tech giants contribute heavily but may steer projects toward their ecosystems. Stay aware of governance models.

• Community sustainability: Smaller projects can struggle with funding and maintainer burnout - support them through contributions or sponsorships.
