Facebook expands @ mention tagging to comments

facebook comments tag
A while back, Facebook introduced Twitter-esque @ tagging, allowing users to mention specific people in posts and status messages. Now Facebook has expanded that same functionality to include comments. The update also provides users with a notification when someone tags them, the same way Facebook notifies you about -- well, about nearly everything.

There's also a benefit for Facebook Page admins. Pages you mention this way are always displayed, making them immune to Facebook's spam filters which sometimes cause regular URLs to be discarded.
