Eli Pariser: Beware online filter bubbles
http://www.ted.com/talks/eli_pariser_beware_online_filter_bubbles.html
The information about the bubble is interesting but I disagree with him as to his conclusion. “Journalistic ethics” did not “get us through the last century”. In fact, “journalistic Ethics” of the last 50 years acted against America’s interests in a radical and destructive way.
“Algorithmic gatekeepers” programmed to apply neo-”journalistic ethics” are much scarier than ones designed to cater to our personal interests — and more scary even than ones designed to steer us towards specific advertisers or services.
Who decides what is “important”, “challenging” or even “different”? I trust Zuckerberg’s judgment on those things even LESS than I trust his judgment as to what my usage indicates would be of interest to me.
