How to apply the patterns of collective-building into an article, a book etc.?

I abstract a shared structure from this paragraph: collectively build x, as new people discover anbd contribute to the project of x, this will continue to transform and grow, so it's virtually never the same x twice. x could be an online community surrounding an article, a video, a book，a QA etc.

My question here is: How can we collectively build an article-community-item, a video-community-item, a book-community-item, a QA-community-item in a way inspired by this Johnny Cash Project?

我从这段文字抽取一个通用结构：集体构建x，当新来的 用户来体验这个x， 并且贡献一份力量时，x不断地改变和成长，x从来没有一样过 。x 可能是围绕着一篇文章，一个 视频，一本书，一个 QA 的在线社区。
