dancing question

every week on my google reader, a headline pops up from cnn stating that another contestant has been kicked off dancing with the stars. why is this news? they don't do this for other reality competition shows. isn't that, like, the whole point of the show...is that someone gets kicked off every week? i've never watched it, so i don't know if when they get kicked off, they actually get plunged into a pit of hungry carnivores, and thus the headlines are announcing the deaths of the 'celebrities' (or something just as serious)....why else would a headline be necessary every week?
