Open Web Docs has raised more than $3m from diverse funding sources for open source web platform documentation. Funds support a small global team, contractors and minor expenses. This talk is a case study on the economics of OWD: how we “sell” open documentation (which isn’t on software dependency lists) and diversify fundraising strategies.

Our docs are living systems, but too often we've imagined them merely as flattened walls of text, and not much more. So, let's take a more holistic perspective of how folks interact with software documentation. Many of them wish to engage more actively, not just as passive consumers. How do we enable them?

Uniting efforts of Apache Airflow, ASF, PSF, Alpha-Omega fund in experimental project aimed at review and help with security of the whole 700+ dependencies of Apache Airflow.

As we increase analysis of our software supply chains, tools and scorecards reveal potential risks in Open Source projects like low maintenance, lack of community, or poor security practices. How should we handle this? Manual reviews? Questionnaires? Funding? Let's explore options to address these challenges strategically without ignorance or fear.
