Both Sides of the Google+ Coin
Ben Brooks’s sentiments around Google’s primary motivation for Google+:
Yes, call me paranoid, but Gruber’s right — Google wants Google+ to be huge, because it is the fastest and most accurate way to better target advertising — of which it makes billions off of doing — not because they want to compete with Facebook.
So Google is offering a free social network that is better than Facebook as well as adding value to their other services, in exchange for being shown ads that are more relevant.
One could say that this is a a win/win situation provided, of course, that the quantity and invasiveness of said ads doesn’t increase as a result.
