Something more closely to what Reddit Live Updaters are doing.

When you scroll to the very bottom of the current page of a thread you're looking at, the website would automatically start loading the next page of the same thread, so that you don't have to leave the current page and be able to view all the posts at once.

If you're on Page 1 in a thread 4 pages long, and you scroll to the bottom, it loads up Page 2, and showing it below Page 1's last post.

How about it?
