The difference is that the people in that Smogon thread are top Showdown! developers who know nearly everything, while people like me only play ladder battles and chat in public chat rooms and not much else. If clutter is the problem, then you should simply leave the thread as soon as you're done posting there, and wait for red things to appear next to the bell in the top right corner. If clicking on the bell says, "<user> quoted your post", then clicking on that link should link you directly to the post that quoted yours.
