Here's an interesting idea ...
In some pieces of software RSS feeds seem to be updated faster than weblog entries. So the feed shows stories as a series of rolling drafts. On your agregator you can watch a story in the progress of being written.
These rolling updates are of smaller granularity than blog-posts. Wonder what that will give rise to (OnGranularity)
JohnRobb says the action is in the agregator : http://jrobb.mindplex.org/2003/09/21.html#a3652
Reminds me that I proposed that newspaper companies buy and brand agregators in MicropaymentsForAndAgainst/DiscussionWithStumblingTongue
