Sister site TUAW mentioned that you can subscribe to a feed and get notified when something new has been added to Apple's movie trailer page. While I think it's great they got this feature enabled I do have a couple of problems.
First, the link that arrives in your RSS aggregator (I use Bloglines) doesn't take you to that specific trailer. Instead it just brings you to the main Trailers page. Kind of goes against the whole concept of RSS as being a method by which to go directly to the content you're interested in. Secondly, you can't (at least not that I saw) subscribe to new trailers automatically through iTunes. Considering Apple's recent foray into the video world (covered extensively on TUAW) this is a bit surprising.
