Might be interesting : one of the coms mention that you can turn off google personnalization. I wasn't aware of that.
I liked the video. Imo he is right from A to Z, it's awesome to have a little more information that are relevant to you (I enjoy more reading about science, audio, etc) but only if you can decide it or not, and only if it's obvious and easy to control. And not by going to an obscure google webpage to personnalise it, whose existence is only known by 1% of people.
I'm not a paranoiac but I'm more and more contemplating leaving facebook, and I'm not using google+, especially cause I wanna avoid the trap of creating a new dependance in a new service. Problem is that so much information pass through fb these days, and you can miss some of your friends info just because you're not a fb-er anymore. Of course people would say "it's up to you to get in touch with your friends", but that's unrealistic and not really the point. Especially like me when you travel a lot or even live abroad.
