I just switched the default search engine in my browser from Google to Bing. And if you care about working efficiently, or getting the right results when you search, then maybe you should too. Don't laugh!
Google changed the way search works this week. It deeply integrated Google+ into search results. It's ostensibly meant to deliver more personalized results. But it pulls those personalized results largely from Google services—Google+, Picasa, YouTube. Search for a restaurant, and instead of its Yelp page, the top result might be someone you know discussing it on Google Plus. Over at SearchEngineland, Danny Sullivan has compiled a series of damning examples of the ways Google's new interface promotes Plus over relevancy. Long story short: It's a huge step backwards.
