I think there were too many "Reply" buttons which has the same functionality. The Reply button below each posts and the Reply button at the end of every thread actually works the same way. It would be nice if the Reply button at the end of every posts can have the same function as the "Quote" button. That way, it would be clear that my reply is actually for that particular comment. It's actually not a big deal but I tend to use the "quote" more because of that. And I only use the general "Reply" button at the end of the thread when I would post a comment in general for that particular thread.
