Those Facebook status update notifications that we've all received at one time or another from the service just got more useful. The social networking site has apparently flipped the switch on allowing replies from e-mail rather than having to log in to the service. All that is needed to do this is replying back to the message itself.
It appears not to be live across everyone yet. I just checked the alert e-mails I've received recently as late as the wee hours of this morning, and I am not seeing the functionality as its being shown by sites such as Download Squad. However it will be rolling out system-wide shortly, reports seem to indicate.
While statuses are now enabled with this feature, Facebook mails - which you'll also receive alerts for - are not. No word from the company on when we could expect that functionality, but I'd venture to guess that's a logical progression for where this feature is headed.
