I know that Xenforo comments have a flat structure, but is there any chance that the forum software will come to adopt a threaded structure (like Reddit)?

Speaking of flat / threaded comments, which do you prefer? Is there a way to have both types of comments be shown for users?

I know that there might be some bias towards flat (as Xenforo's userbase is accustomed to flat comments), but it would still be nice to know as to which you prefer and why.
