Mad At Google? The Question Is: Are You Mad Enough To Stop Using It? Can You Even Stop Using It? http://www.crunchgear.com/2010/08/10/mad-at-google-the-question-is-are-you-mad-enough-to-stop-using-it-can-you-even-stop-using-it/
One of the many items discussed in the “brainstorm” documents: will Google create a “Like button” that follows you around the Internet, dumping all of that “like” data into a giant database that it then hands over to the highest bidder? What’s to stop it from doing so, and does that bother you?

Posted this ’cause it is interesting in its own right but also because of how the quest for the perfect collaborative filtering is still not achieved. I reckon someone might build it on top of everything. Open source would be best. Wikipedia style collaborative filtering network based on algorithms that know what you like because others like you like it.
