A few days ago, I noticed in my emailed Facebook status update notifications, that I could now reply to them via email. That is, I could reply to a friend’s status update without having to go to and login to Facebook. I thought it was interesting, but could not see the immediate benefit to me. Nevertheless, I started using the new feature.
Later, after talking with someone about how Facebook has become a popular vector for PC viruses and how many companies are beginning to block Facebook access for workers, it struck me! Being able to reply to a status update or comment on one via email is a way to get around the block. Keeping people from sending email to certain addresses is a thornier issue than blocking access to a particular web site. And it is highly unlikely that mail from Facebook itself poses any kind of security threat. Still, people are supposed to be working, right? Facebook you are so cheeky!
