Threaded view is the default way to view threads on the forum and reasonably so. Between the two modes of viewing, it's the more useful one, allowing users to see who's responding to who. The CYS forum format doesn't really work well with non-threaded, and there's nothing to really benefit from the alternative except to see what order posts where made, but there aren't a whole lot of uses for that anyways. We should have the option to have non-threaded view removed, and in order to make up for any potential losses, a feature that shows the time a post was posted could be implemented.
