Obvious to many, many are completely unaware of the nofollow attribute in a link. The use of nofollow could be a good poll as well. Originally developed to stop bots from following a link, Google seems to think its main purpose is to identify paid links.
Personally, I believe it should be used for its original purpose, and that Google’s lack of ability to recognize a link as a “paid one” simply reflects that one of its methods to identify a valuable site needs to reconsidered. If Google expects webmasters to identify a sponsor, why not use something like rel=”sponsor”? Google or other search engines can then choose how to handle the attribute personally.
Here a direct link to the poll: Do you know how to use the nofollow attribute in a link?
