Why do posts get frozen/archived on reddit?

Off-topic I know, but how many of you out there get annoyed when you find a given post on Reddit, only to find there's no longer any way to respond because the thread/question has been locked or archived? I don't understand why this happens. Not all of us find a given thread during the limited window that it's open for contributions - many questions remain legitimate years after they are posed. I don't understand why we can't keep adding to or refining knowledge or whatever on these topics. Surely storage limitations can't be the reason. Anyway, perhaps I'm just shouting at clouds.
