itunes lets you watch videos and listen to podcasts. These experiences get delivered. I think a lot of people like delivery. Whether its pizza's or newspapers, there is a market for the convenience of delivered stuff.
Web content is no different, short form video, blogs, music etc. People are excited to run around and check out the latest YouTube video. What if it showed up in their inbox as a stream of cool stuff.
That is what RSS does. RSS is great idea spoiled by a horrible name.
RSS is going to get a lot better for the average person as it disappears and is replaced by "feed". Feeds and the concept of delivered content will make this happen.
The company I work for makes a tool that creates a media inbox in Outlook and Outlook Express. That means that when you are working with e-mail you can check out that latest film clip, music video or cool blog.
If you are a content publisher it is powerful to delivery content. Instead of having to drag people to your site all the time and hope the home page is "cool" enough, people sign up for a media feed they care about. This feed could be artist based, keyword, thematic, most popular etc. whatever the end user deems quality content, yes even a full media feed of mentos and diet coke videos.
According to the latest data the average major video site got 17.8 views per month. If each video averages 3 minutes of consumption that works out to 105 seconds of viewing per day for the major sites.
