I'm surprised they haven't brought this in with an option so people can rate or at the least flag sites. Source users feedback directly which would probably help wipe out results like Pintrest that dominate so many searches but people find unhelpful.

It would be great if they had an option where they have the drop-down for cache to say something like 'dont show this domain' or something that would let people flag sites that dont seem to offer value against search terms

Also on the 'computer' search I was amazed how everything was now in a left column and how much blank space on the right there was: http://prntscr.com/pw5iav - is that mobile optimisation overtaking desktop experience?
