Facebook Now Suggesting Friends Found in Imported Contact Lists?

Facebook has been using its “Suggestions” area of the home page to recommend friends you may know for a while now (and more recently, suggested public profiles you may like). While Facebook has traditionally calculated its list of “People You May Know” by analyzing the social graph – choosing friends of friends, etc. – many users have started noticing this week that Facebook appears to be suggesting people not because they’re friends of friends, but because their contact records were imported using Facebook’s “Find People You Email” feature at some point in the past.
