Today is thanksgiving in the US and Mark Zuckerberg took to his FB page to share what he is thankful for this thanksgiving. He said:

Priscilla and I have a lot to be grateful for this Thanksgiving and holiday season, and family is at the top of our list. This is a big year for our little family, and we're so filled with hope for all that's ahead.
Reflecting on family, I want to share this photo Annie Leibovitz captured with my parents and sister last month. I'm looking forward to many more moments with family to come.
