Dave Winer is talking about his "River of News" again....
My first river of news aggregator first appeared in 1999, when RSS was new. I've been doing them ever since. This was the week when the concept finally caught on, imho.

Scripting News: 8/24/2006.

I've said it before, and I'll say it again - this is the only way to read news. It liberates the reader from the shackles of folders of unread messages and very casually drops unread (and read) items off the bottom of the page. It is a very comfortable way to read news. So comfortable in fact that we made “River of News” the default view for both Skydasher and Skydasher: Mobile Edition (except we call it “sort by timestamp” – with the other view being “sort by source”).
