Facebook's Bug Spreading

(2/8/2013) I also got caught by this bug when I tried to share some weather information on my facebook. Webpages are forced to close after that failed sharing (Weather.com, Huffingtonpost.com..) . I guessed that was a Weather.com website's sharing issue. Now we know it's Facebook's bug. Gee, a mistake of Facebook can take down so many sites. I learned a new lesson.
