Just enter your Youtube username and hit the button to create a RSS feed with embedded movies of your Youtube Favorites.
What is it good for?
YouTube offers several feeds, but not for your favorited movies. Through the form above you can create a RSS feed which let's you subscribe to your (or your friend's) favorited YouTube videos. I use it to include my YouTube favorites within my soup (which is a new TumbleLog service). That way I don't have to submit each video I like to soup - I only have to hit the "Save to Favorites"-Button on the YouTube-page.
