response: Nice.  I understand that one can view, upload, rate, share, comment and report videos.  And add to favorites too!
original_response: you ever upload your own videos? Youtube allows anyone to do that since they first came out.
history: I love to surf youtube, I always end up watching interesting videos on there. Oh do you? Jawed Karim, Steve Chen, and Chad Hurley created it in February 2005. I dont' know when I first discovered it, but I watched at least an hour videos on there a day.
knowledge: YouTube allows users to upload, view, rate, share, add to favorites, report, comment on videos, and subscribe to other users.
