Facebook Demotes News Feed Preferences
Two weeks after it removed per-story (thumbs up/thumbs down) preferences from the News Feed, Facebook today further simplified the News Feed interface by removing (update) moving the Preferences link to the bottom of the page. News Feed Preferences allow users to indicate types of stories and people that they want to see more or less news about.
Apparently, while powerful ideas in theory, when taken in conjunction with other factors in Facebook’s News Feed algorithm both general and per-story News Feed preferences must not affect user satisfaction significantly enough to merit their presence. Facebook is apparently able to do a better job of choosing the right feed stories for you based on your behavior rather than the preferences you express – a significant technical accomplishment.
