I blindly predict we are going to see an announcement soon, that if your search results are poor, you need to login to Google (and get your free G+ account) and allow them to personalize your search, which will guarantee better results.
I agree...but a very, VERY, VEEEEERY bad move on Google's part if they try to herd us to G+. People are not using facebook like they used to, yet we are being force fed all these social apps and junk we're supposed to add to our sites in order to "fit in" and rank high from our "social interaction". That model doesn't fit every business.
Larry Page made it clear, Google wants user love, but as Bruce Almighty found out the hard way, you can't mess with free will.
