At the end of June a vulnerability in Facebook’s security was revealed. Nikolas Coukouma has a full technical overview if you are interested in reading more about it. After being notified on the 30th of June Facebook finally resolved the issue yesterday. I think Facebook’s productivity has dropped drastically since the platform launched. I listened to Mark Zuckerberg’s sister, Randi, talk about the drop in productivity over at Facebook in an interview with Robert Scoble.

I also have experienced a reduction in productivity as a result of Facebook. It’s kind of incredible how much time I have been spending on Noggin, the addictive game that I wrote about a couple of days ago. Randi Zuckerberg says that she thinks Facebook’s productivity has dropped by 50 percent and she may just be right. Have you been experiencing a reduction in productivity as a result of Facebook? Also, what are the biggest time killer applications for you on Facebook?
