In a post on Burning Questions, we talked about how popular our feed splicing services are, and offered up this perspective on where we think things are going:
[F]or some, the feed is becoming a first-class citizen in the world of content, and FeedBurner wants to help. Feeds pretty much started out being a lightweight content transport, or a notification mechanism. This remains a completely valid and appropriate use of feeds: as an extension of your web site that draws users to visit your web-based content. But as publishing tools begin to specialize ("I keep my photos on Flickr, my blog's with Blogger, I use del.icio.us to store my links, and then I've got my calendar, NetFlix queue, Amazon wish list, and so on and so forth"), it starts to get harder and harder to point to a single URL and say "This is me." The one thing that all of these content sources have in common, however, is the ability to provide a standardized representation of themselves as a feed. A FeedBurner goal is to help you collect and manage the "scattered pieces of you" into a single resource that can easily be shared with others. The feed starts to become much greater than the sum of its parts.
Now, that talks about a feed being a distinct entity composed of a number of point sources, but it's not hard to imagine directing this flow of information at some endpoint that, itself, could be some kind of CMS. There are a number of very interesting implications of being able to decouple the points of content creation with its management and hosting, but that's for another post.
Erik Benson, of All Consuming and 43 Things fame, recently did some cool personal content consolidation using Bloglines as the integration conduit. Check out his posts "Outsourcing the blog" and "Using Bloglines to manage my online presence".
This meme has been floating around for a while (see also "more thoughts on similarities between software packages" and "Interweb connectivity through ping-/trackback"), but Erik's duct tape implementation is the first real implementation I've seen outside of MT plug-ins. Nice job!
