I'd like the ability to share part or all of my data to anyone, privately or publicly. And in the case of data I share publicly, I want it to be available on a page that is indexed by Google and doesn't require someone to login with a Google account.

Also, I'd like to see Google rank sites in a similar manner to Alexa, but with real data. I know that Quantcast does this, but having both GA and Quantcast JS beacons on my site is a waste of my users' load times and privacy.
