It makes my head hurt to think what my social graph probably looks like. And personalization apparently means that I'm going to be followed around the web by a giant glazed donut (one of those local coupon sites) for the rest of my life. Because I see it everywhere I go.
How is this a better user experience? I don't get it.
I try to avoid being logged into one of my 20 or 25 Google accounts (mostly for clients) as much as possible. I don't need more glazed donuts or Russian women in my life.
