First, the author doesn't have a Google+ invite (neither do I, sad face). Makes speculation extra hard. I think the privacy issue is the Achilles heel of Google+. Remember when anonymized queries were released for research purposes were released with gems like "kill my wife zipcode 94234". Well, now you have everything in one package: your location, searches, email, business infrastructure (if you use Google apps), pics, etc. Google+ is the end of the "don't be evil" era. Not because they are evil now but because they're pulling out all the stops and not putting data in silos (even for show). Google+ is a lot more scary than Facebook because of the algorithmic component. Going forward, their products will integrate with Google+ by default making it harder and harder to divest yourself from being tracked. They will make money off of this information, the question is how.
