It seems that beyond carrying syndication information, RSS is a very useful and flexible way to get all sorts of application data pushed to a user over time. In the same way that a web browser is a universal canvas upon which limitless services and information can be painted, so (in an albeit much smaller way) an RSS reader/aggregator might also find its place as an inbox for time-related delivery of all sorts of information.
My thoughts exactly. Not sure if I've posted here about it, but I know during the whole RSS hubbub this fall, I'd babbled something about RSS being a messaging queue from machines to humans. Or a transport for timely ephemera to people. Or something like that. Basically, I'd like to see RSS, or something like it, used beyond just headlines. This is why I've leaned toward the RDF-in-RSS camp - I want to see lots of things besides titles and excerpts hung off the individual message events, and RDF seems downright nifty to me for this.
But either way, I like the expanded notion of RSS usage as a timestream-oriented stream of messages targeted at subscribed people.shortname=ooocib
