Short Ted Talk by Pariser on the "filter bubble"

FYI: here's a 9 minute TED Talk by Eli Pariser on the "filter bubble." It's not as complete as the article, but it's a succinct discussion of problem of "invisible algorithmic editing" (or personalized/ tailored filters) by Google and Facebook, aimed more at news and what we "need" to know vs. what our filters assume we want to know.
