Thread:Feedback/Reply to message and Add Message

Many forms provide distinct tools for replying to a message as a sub-thread and adding a message to a thread at the same level. Some even make adding the default action so that it takes an additional, deliberate action to create a fork. This helps to avoid superfluous nesting in an essentially linear thread, especially in lengthy discussions where one would need to scroll up to reply to the parent node.

In the old wiki discussions, people tend to use indentation to visibly delimit messages as much as to indicate semantic nesting. The new boxed messages remove a leading cause of superfluous nesting that tends to run off to the right, with the occasional "outdent," and to obscure the significance of meaningful nesting.

Making the affordance for "add at the same level" at least as prominent and convenient as "fork on a new level", if not moreso, would leverage this improvement further.
