Facebook’s EdgeRank
So “EdgeRank” is the algorithm that powers your Facebook News Feed, and it’s also what attempts to maximize your time spent on Facebook. Instead of delivering the quick-consumption updates you actually want to see (status, explicitly shared items), it barrages you with items that are likely to keep you engaged, attentive, and ad-click happy…
Update, July 27th 2010: A comment I left in response to a friend wondering why nobody responded to his status update:
It’s not that your FB friends weren’t interested, it’s that Facebook’s “EdgeRank” algorithm that powers the News Feed predicted that this wasn’t engaging enough, thus worthwhile, to show in most of your friends’ News Feed.
