If you’re attending virtually, treat the agenda like a technical conference, not a product launch. Pick a few sessions related to problems you’re actively solving, note one concrete idea from each, and test it in a small repository afterward. The most useful sessions will probably show real workflows involving agents, code review, CI, and security, including where the tools fail or still need human judgment. Compare the demos with your own development process to make the event practical instead of just collecting announcements.
Some of the events are available for free if attending virtually. Plus, you get to hear insights directly from GitHub staff and people using the various tools and workflows.
Most of the money from tickets goes towards non-profits and funding open source. A part goes towards venue and logistic costs.
