Eli Pariser: Beware online "filter bubbles", TEDtalksDirector, May 2, 2011: As web companies strive to tailor their services (including news and search results) to our personal tastes, there's a dangerous unintended consequence: We get trapped in a "filter bubble" and don't get exposed to information that could challenge or broaden our worldview.

Always go to the source. If you write a blog, always link to the source.
