Websites such as Reddit have tiered comments. In tiered comments, a response is indented one step past its parent comment. How can tiered comments be adapted for the mobile screen? I forsee the following problems from transferring this website idiom directly to mobile:
- The narrow screen width limits the depth of conversations.
- The narrow screen height limits the user's global mental map of the conversation. That is, the user may lose track of who is responding to who when the originating comment is not visible on the screen.
- The indentation is ostentatious use of white space on mobile screens. Are there other ways to show hierarchy without using vast amounts of white space?
