Aside from Youtube&#x27;s copyright system, I also hope something like this works out because of their UI. I mean, let&#x27;s face it. Youtube just seems to change their layout and features every few months or so, regardless of whether they make the site easier to use or not and regardless of what anyone actually wants said changes.<p>If Amazon can come up with a good, user friendly UI and then not screw it up by making constant changes, they could do quite well here.
