I (well, my colleague Kenneth) noticed that YouTube has some nifty new features. Start the movie below (as an example):
[youtube http://www.youtube.com/watch?v=hVf2bUIv6FY]
At the bottom there's a Mac-style menu with related movies. You can simply navigate through all related movies ... which in this case gives a nice list of movies we (ONE Agency) have put online (and also some unrelated crap :)). At the end of the movie there's are some new features too.
UPDATE:
New features disappeared again :(
