The thread was spawned by the New York Times' recent editorial exploring YouTube's role as "one of the most powerful radicalizing instruments of the 21st century."

For example, YouTube and Google's autocomplete boxes deliver starkly different answers, with the video site recommending controversial or fake points of view on YouTube.

YouTube results are on the left while Google results are on the right. Both searches were done in Google's "incognito mode" to prevent the results from being affected by prior search history.
