The Next.js 13 documentation has been made more collaborative by enabling the new Vercel commenting feature in beta on its docs, allowing over 2,000 developers to leave feedback with 509 discussion threads and 347 resolved issues. This feature enables teams to ship faster through streamlined feedback loops, addressing user feedback directly without adding extra tools or defining additional workflows. The commenting product was originally designed for private usage but has been successfully used in public sites like the Next.js Conf page and weekly changelogs, providing improved context and enabling the team to quickly understand the exact parts of the UI that need improving. With comments on Preview Deployments, teams can handle a larger amount of feedback without feeling overwhelmed, act on feedback faster and more precisely while spending less time figuring out where issues are located, and iterate on improvements faster than ever.
