Facebook has just launched its retweet version, giving an opportunity to share news and feeds “citing” your source of information. The Facebook retweet option is just like the Twitter retweet… but in Facebook. The “via” feature lets you repost another user’s shared items, with a “via” link attached for attribution.

To try the feature, just go to a friend’s posted item in your news feed, click “share,” and you’ll see a “via [your friend’s name]”. There is, of course, an option to remove it. Once shared, the item will appear on your profile, with a “via link” that points to your friend’s profile. Your friends will also see the item in their News Feeds, creating the viral loop that is the Twitter retweet.

The feature is currently live for everyone, but it only works for posted links – you can’t “via” someone else’s status update or photo. Marketers claim it’s a big move for Facebook that makes its service even more Twitter-like. The same way Tweetmeme tracks the number of shares and retweets, we’ll be waiting so similar Facebook application.
