Wake up and smell the algorithms

Hey all,
First and foremost I must point out that the title for this post isn't mine; it was a tweet I found (by @davebarbush)on the TED Blog along with this great video of a TED talk given by Eli Pariser about the tailoring of your internet searches and how what you might think is an open book is in fact filtered to the nth degree. If you have a spare 9 minutes it'll tell you how algorithms are the new librarians/journalists! Enlightens and entertains in one go.
