I think people reading slowly has a lot to do with it; people just jump onto the first relevant-looking item they see. They saw the Facebook button and didn't read the stuff that was obviously a written article. Something else I often see, which I think has the same cause: people blindly clicking on the first item returned by a search, when the second or third result is clearly what they're looking for.
