I think one-thread structure is good enough already, and replies to replies make conversations messy (just like blogs). I personally believe that the best way to "branch" conversations is by allowing them to morph into separate threads in their own right (yes, just like Branch). Keeping everything in the same thread is bad for a couple of reasons:
 * Lack of a definite topic
 * Lack of TOC that points to branch-offs
 * At some point, the thread title is no longer informative of the actual conversations ongoing there

It would be useful if instead of replies to replies people could branch topics by creating new threads as replies to posts. The first post, and the thread name, of the new thread would be created by the person replying to a post, but the UI should also show the post the thread was created as a response to, as well as point to the new thread from the original post. I know I'm essentially describing Branch right now, but the idea was just floating in the air.
