Here's Dave's announcement on the categories feature I mentioned earlier: New Radio 8 feature. Now you can post to categories without posting to the home page. If you have categories enabled, there's a new checkbox, the first one, called Home Page (it effectively becomes a category). By default it's checked. Now you can easily publish multiple weblogs, going to lots of different locations, from one edit box. Screen shot.  [Dave Winer: Radio UserLand]
