Facebook Takes Cue From Twitter With “@” Sign Syntax

Making like a good social network and copying its competitors more successful aspects, Facebook has taken the liberty of using the @ symbol to tag friends in posts and status updates, a method that was popularized by Twitter.
Currently, while on Twitter you can use the @ symbol to refer to, or directly respond to a friend (ex: Hanging out with the coolest guy ever, @asalisbury). And, exactly as it’s done on Twitter, Facebook will reportedly auto-generate names with you enter part of a friend’s name. Don’t worry though, if the status update is too embarrassing you will be able to untag yourself.
The new feature is available now, so feel free to go give it a whirl.
