Last year, Thanksgiving saw Instagram's busiest day in its history. At its peak, over 200 images were being uploaded to the photo-sharing site every second. This year, when Thanksgiving and the first full day of Chanukah (but not the first night) co-incided, that record was broken again. Instagram hasn't divulged exactly how many photos of turkeys, latkes, and chanukiahs went through its system on Thursday, but we know it'll be more than 10 million. It's on its blog.
