This could have far reaching effects at some point. Roll out is ongoing right now, you may not have it yet. Link
http://www.youtube.com/watch?v=t8Pl1H0dIXE . Type in "john bridge" into google, when search comes up scroll to bottom of page and click "See all notes for this searchwiki". This service by Google also allows a user to delete search results they do not want showing up. Up arrow and x box to right. I'm sure these results of deletion will somehow show up in Googles search algorithm. Possibly having sites voted down in the search results.
What your take on this? .
