In Google's original concept, a naturally-acquired backlink is equivalent to a "vote". Some votes count more than others, but all should be counted to some extent if they are voluntarily given and intended to be a recommendation.

The problem is that some voluntarily-given votes are not being counted because many forums and social-networking sites automatically add a nofollow tag to the link.
