User-submitted content (e.g., stories) may be associated with descriptive metadata (intersection metadata), such as a timeframe, location, tags, and so on. Story content is presented in a virtual space, such as a forum, chatroom, or the like. Users submit collaborative content as the story is presented in the virtual space. The collaborative content is synchronized to presentation of the story. An author may replay the presentation and synchronized collaborative content and/or select portions of the collaborative content for inclusion in the story.
