Did you seriously ask how would Google know that the content on a Google-indexed website has changed?
#facepalm
Google does not have the entire web every second. There are gaps.
It's a nice idea, but I see a couple problems:
1. The rights holders likely subcontract out the actual take-down notification services, perhaps more than one.
2. An infringing site today may be no longer infringing when the request is reviewed. That is, the site may change between the time the take-down request is generated and the time Google actually reviews it. How would Google know?
does this theory mess up any of our current Radiometric dating (and other similar) methods?
I was wondering the same thing. Another reason for the Creationists to argue that the carbon-dating is all wrong and the Earth is young.
Not entirely true. Some Facebook pages (like mine: http://facebook.com/lannocc), are publicly viewable to anyone (as long as you're logged in). I actually wish FB would remove the logged-in restriction so my page could be searched and accessed by any person or web spider.
However, your other idea about hosting your own personal data is something I like and have thought about frequently. I imagine a social web of providers where you can pick a storage provider (or provide your own) from a marketplace. Some would be free, probably ad-supported. Others might take a small payment but guarantee an encrypted store with options for key delegation in the event of death, etc.
