Two questions about nofollow
On February 26, 2009, Google software engineer Matt Cutts collected questions on Google Moderator and answered many of them on video. Vince Samios from the United Kingdom asked: Do you feel that the widespread and blanket use of nofollow tags is devaluing Google's search algorithms?
