Stage 6, the YouTube-style site for high-quality video uploads, which we had flagged before as an example of a challenger to YouTube's crown has sadly decided to close as of today (28th Feb).  The news was broken by a statement posted on the site;

In many ways, though, the service did succeed, beyond even our own initial expectations. Stage6 became very popular very quickly. We helped gain exposure for some talented filmmakers who brought great videos to the attention of an engaged community. We helped prove that it's possible to distribute true high definition video on the Internet....So why are we shutting the service down? Well, the short answer is that the continued operation of Stage6 is a very expensive enterprise that requires an enormous amount of attention and resources that we are not in a position to continue to provide....We couldn't continue to run Stage6 and focus on our broader strategy to make it possible for anyone to enjoy high-quality video on any device. So, in July of last year we announced that we were kicking off an effort to explore strategic alternatives for Stage6, which is a fancy way of saying we decided we would either have to sell it, spin it out into a private company or shut it down....Stage6 will cease to exist as an online destination. But the larger DivX universe will continue...
