Today, as announced on the Google Blog, we're excited to roll out the Google +1 button on YouTube. The +1 button will be available to everyone on the YouTube watch page under the Share feature. If you're signed in, you'll also be able to see +1 annotations from your Google contacts on YouTube search results. We believe letting users see videos recommended by people they are connected to will be incredibly valuable in helping you find and watch the videos that matter to you.
