what do you think of meaningless posts?

I've seen stories/question that are only one sentence or phrase and totally meaningless such as "I'm watching TV now" or "what's your height?" , and when you check the author they got thousands of posts that are mostly the same way. Does Sw give points or some kind of advantage for the count of sorts? Or is it just people who are so empty minded, bored and decided to project their boredom on others?
