Weve long speculated as to when Facebook might get its own version of Twitters retweet, and it appears that the time is now. This evening, the site rolled out a via feature that lets you repost another users shared items, with a via link attached for attribution.

It appears the feature is live for everyone. To try it, just go to a friends posted item in your news feed, click share, and youll see a via [your friends name] (with an option to remove it). Once shared, the item will appear on your profile, with a via link that points to your friends profile. Your friends will also see the item in their News Feeds, creating the viral loop that is the Twitter (Twitter) retweet.

Currently, the feature only works for posted links you cant via someone elses status update or photo. Nonetheless, given the most visible use of retweets on Twitter is links, with aggregators like Tweetmeme (Tweetmeme) tracking which stories get retweeted the most, its a big move for Facebook (Facebook) that makes its service even more Twitter-like.

Where the feature goes from here, were not sure, but given the social networks ambition to make more and more of what you post public, its clearly another attempt to become more relevant in the world of real-time news, search, and information. Whether or not users respond and start posting shared via links (is that what we call them?) will also remain to be seen.
