Well compare that inconvenience to this: Writing a message for more than 10 minutes or leaving the keyboard for more than 10 minutes and have all the still unread threads marked as read across all subforums. So now you have to figure out what time it was when that happens, and in each subforum you frequent, scroll down to find the post that was newer than that time and start from there. But that's not all, now when you want to look at new posts in a now shown as read thread that interest you, you have to go to the last page and scroll to see which posts you haven't read (go to first new post won't work here since the thread is show as read), which might be in a previous page so keep going until you find that post. That is very annoying.
