Dave Winer has ideas:

ideas for rethinking blogs and feeds. I found, as others have, that I need another kind of document to include in my personal CMS other than a story that’s part of the blog. Everything about blogs are set up to be written, then lightly edited, and never touched again. It’s temporal writing. But there are other things that I want to develop over time, keep coming back to, revising. A few years back I started this.how to hold those docs.

He’s talking about what I like to call ‘web pages,’ surely? You don’t need any fancy CMS for those, as Dave of all people should know. And if you want to use such a thing, well, even WordPress has its Posts/Pages distinction.
