As Mark Zuckerberg reflects on Facebooks first ten years as a company today, hes encouraging the community he built to do the same. Starting this morning, hundreds of millions of Facebook users will receive a notification that a video summary of their life so far on Facebook is ready to watch. The videos are a bit cheesy, but are potent reminders that for many of us, Facebook has become a very normal way to document our daily lives. A small team at Facebook spent the last few months crafting the videos and ensuring that the company had the necessary resources to render hundreds of millions of HD videos and send them out to users.
