Notice: The new YouTube breaks SubTube; as a workaround, set your User-Agent to an older browser like Internet Explorer 7.
SubTube is a self-contained webpage that gets the latest videos from YouTube channels you like. Unlike YouTube's subscription feature, SubTube doesn't require you to be logged in. You can save this webpage as a plain HTML file and use it locally.
For each user or channel on YouTube that you want to subscribe to, add the channel name to the text area above. To figure out the channel name, go to the channel's YouTube video page and look at the URL:
If the URL contains "user", enter the channel name that follows it without any changes. For "youtube.com/user/apple/videos", the channel name is "apple".
If the URL contains "channel", enter the channel name prepended by a "#". For "youtube.com/channel/ABCDEFGHIJKLM/videos", the channel name is "#ABCDEFGHIJKLM"
Seperate each channel name with a comma and no space.
