Google Plus is more than a social network. It's an identity service. That's why Google hasn't seemed particularly bothered when people rag on Plus for being a backwater, or push back about forced Google Plus integration. Google gets a lot out of information out of knowing who you are when you create content online and do other Internet-y things, and it's not giving that up.
But is there something afoot? A recent New York Times story about Plus says:
Before Google released Plus, the company might not have known that you were the same person when you searched, watched videos and used maps. With a single Plus account, the company can build a database of your affinities.
Bradley Horowitz, the vice president of product management for Google Plus, tells the Times, “Google Plus ... gives Google that common understanding of who you are.” That sounds terrifying, which is why ValleyWag headlined its story, “Google Admits Google+ Was Just A Ploy To Track Your Behavior Online.”
But Horowitz isn't really admitting anything. Google has been up front about this strategy for 10 years, which in tech time is pretty much an eon.
It's true that since Plus came on the scene in June 2011, Google has focused significant development power on integrating data from Plus so it can sell more targeted ads and figure out whether you're searching for Owen Wilson the celebrity or Owen Wilson your high school friend. But Google was on to you long before Plus ever came along, and your central Google login could endure if Plus were to suddenly disappear tomorrow.
