Families and teachers rejoice! Youtube has filled a gap in their service by adding the option to upload a video that is viewable by non-Youtube account holders, but is not accessable to the public via search results or in user pages. Essentially, to view the video, you either have to be the account holder, or have been provided with the URL. This should be a great option for teachers to communicate with their students, and for families to share video without making them public or requiring the recipient to create a Youtube account (which, prior to today, were the only ways for others to be able to view Youtube videos).
