[Audio: English; Captions: Arabic, Chinese (2), English, Italian, Romanian (see link below)]
I love TED’s videos, but I find it very frustrating they don’t appear to make the subtitles available via embedding! The talk, with its captions, is available here: Eli Pariser: Beware online “filter bubbles”.
He’s also got a book out: The Filter Bubble: What the Internet Is Hiding from You which I’ll be reading as well. (The book link will send any proceeds from the sales at Amazon to Moveon.Org.)
