It could not. "liking" is inherently biased. It is in no way an objective measurement of usefulness. Pages that contain negative content will never be "liked" even though they might be very useful or linked to a lot. As an extreme example, say a mass-murderer becomes very famous. No one (except for a trolling few) will "like" a page giving information about him, like on wikipedia. But this page would be a lot more interesting than a sensationalist article describing him as the second and third coming of Satan, which would be "liked" a lot more, without really being more valuable.
