It depends on what you mean by "junk article". If it's an article that cannot possibly prove useful to a future editor, then yes, it should be deleted. Most stubs aren't in this category, though. If it's an article that is not good *now* as an article, but might be useful to a future editor, then it shouldn't be deleted---instead we should develop some sort of labeling system so a reader who stumbles onto it is properly notified that this article is very much a work-in-progress and not yet ready for serious use as a reference.
Perhaps we could put a template of some sort on it. How about {{stub}}? We could develop a system of subtypes if that category gets too full to work with.
