Why is Yahoo Answers so popular? Especially when the quality of it appears lacking?

Yahoo Answers reminds me of a kindergarten with no teachers. It’s a hopeless mess and the “students” can’t spell to save their lives. Also, there is so much squabbling that a decent question is lost in it all. For those who use Y!A, sorry, but this is the way I see it from my experience.

It makes me wonder: why is the site so popular when good results are practically non-existent? What attracts people to it? If anyone out there has yielding anything helpful from Yahoo Answers, how did you do so?
