Filters by the Websites on the internet

Very interesting session from Eli Pariser at TED Conference at Long Beach, CA in Feb.2011. He talks about the privacy and filters that are pulled upon us by the biggies like Facebook, Google, Netflix etc. Our clicking/surfing patterns are always interpreted by some complex algorithms and gives us a refined/altered/filtered data. Watch the video...its of good quality and short (9.05min).
