There is an option of long threads at the bottom of each page. These are sorting options, and you can sort them by date "Descending," rather than "Ascending," making the newest posts show up first.
There is also a link at the top-right, by the page numbers (if you have already visited the thread), that says "First Unread Post". That will lead you to the oldest post in that thread that you supposedly have not read yet.
