Inspiration

Inspired by Ben Balter

This site draws inspiration from the work of Ben Balter, Director of Hubber Enablement within the Office of the COO at GitHub. His thoughtful writing on GitHub's culture, work practices, and open source leadership has influenced both my professional approach and my content style.

Ben's post on The seven habits of highly effective GitHubbers particularly resonates with me as it captures the essence of GitHub's unique work culture through traits like being "professional, but not formal" and the philosophy to "ship early, ship often."
