When you become a YouTube member, YouTube assigns a personal channel to you. The channel has divisions designed to display a short personal description, thumbnails of videos you've uploaded, members to whom you've subscribed, videos from other members you've picked as favorites, lists of members who are your friends and subscribers and a section where other people can comment on your channel.

You can visit another member's personal channel by clicking on his or her user name. Here, you can view all of the YouTuber's videos as well as all the videos he or she picked as favorites. You can even see the other members to whom the YouTuber has subscribed. Personal channels let you explore YouTube as a social network rather than as a simple video database -- you can find users who like the same kinds of videos you do and find out what they are watching.
