I'm one of the few active users of Google Wave. I'm all about the tracking of history so I can see how an idea evolved. I used to use local text files, but I didn't like that they weren't available on the web and could easily be buried on my desktop/documents folder. Wave also has rich formatting and supports inline attachments. One caveat - you can't really export out of wave easily.
