The Great Dave of Weblogs is talking about Blog Browsers, which would let one view a Weblog using a simple UI. Could fit into the stuff I've been doing. I've been thinking of adding some generic XML handling just for those non-RDF RSS files (and for other things of course).
I'm not sure why this Blog Browser Dave refers to needs an archive though. Would be nice to only need to send the data the user actually is viewing at the time. I think RDF would better let one return as little or as much as one desires.
By the way, you can get an RSS version of any portion of my Weblog (except the static index page) by adding '&format=rss' onto the end of the URL. Use '&min=X' with some number X to indicate the number of items to return.
I've added some UI to do this. You could, I suppose, set the minimum count to some large number to get an archive to use for the Blog Browser.
