Mapping a Digital Tradition

I wonder if alternative paths in composition can be paved through a variety of digital forms (modes, assignments) with specific purposes and a better understanding of audience. When interaction between audience members (peers & instructor) is limited to communication through composition only, then each interaction (post, comment) is a rhetorical opportunity that requires a student to quickly consider and negotiate audience in an unpredictable composition environment where any audience member or members (peers or instructor) can appear in a conversation at any given moment—forcing the student writer into immediate writing choices, which practices and improves their rhetorical skills.
