Probably those depending on 1st place SERP listings need to adjust more to the times. Google is seeking to take much more control of the navigation / usability elements used in conjunction with content.
Flat content in many verticals that produce lot's of traffic for Google are fair game. Location based services seem to be a prime target , and I'm not sure if Adwords will provide a cost effective alternative to many wanting to counteract this.
Best to find a way to go with the flow.
