+Summary: The day before GopherCon, a group of Go team members and contributors gathered in Denver to discuss and plan for the future of the Go project. This was the first ever event of its kind, a major milestone for the Go project. The event comprised a morning session revolving around focused discussions on a theme, and an afternoon session made up of round table discussions in small break-out groups.
