Youtube: Broadcast Yourself.
A website to talk, and make friends, as well as having every video you could ever think of watching.
Has almost every song or comedy clip, ever created.
Sort of like myspace, you can edit your channel, make friends, send messages, write about yourself, but is more centred around those who have a similar interest, and rather than adding your
real friends, as you would on myspace, you add other people who are
interested in the same stuff.
You can share videos, make videos, post them on youtube, and tag them, as in
photobucket and tinypic.
