Hmm. With Word, for instance, virtually every correction to the text results in a huge clutter of change-tracking notes about format changes and similar drivel. For many documents, it makes the S/N ratio just miserable. If there were a "track substantive textual changes only" option, an "ignore format changes" one, or some sort of "accept all format, font, and style changes" command, I'd probably agree with you about utility. But, given the reality of those systems today, I tend to agree with Ned, even though I like a feature of those system that you didn't mention (the ability to insert comments whose appearance in the output can easily turned on and off. <cref> and some processing options comes close, but isn't quite the same). [YJS] My experience has been quite different. I work, on a daily basis, with many extremely complex Word documents each of which is handled by many different people (often with conflicting aims). These documents often go through dozens of revisions. And although (as mentioned often before) I am no great fan of Word, I have never seen S/N problems of the type you mention. I suspect that your co-authors are really fooling around way too much with presentation aspects rather than content. Next time agree on a ground rule that first the ideas should be gotten right, and leave the pretty-printing for the final round. Not only does this make sense and save everyones time, it will probably eliminate your S/N problem.
