Ned, as an AD I read dozens of documents a week and offer suggestions on those documents. These changes frequently require negotiation, but for AD reviews specifically, not having change tracking means that if I offer a heavy edit on a particular document, there's a good chance I'm just wasting my time, because the author won't bother to integrate it. Something that makes this as easy as change tracking in MS word would _substantially_ reduce my workload while at the same time increasing my effectiveness. I agree that if you are only editing one document every so often, it won't make much difference. The other thing an easy tool might do is make it easier for IETF participants to usefully do reviews, meaning that we might get more reviews. It would in particular make it much easier for working groups to collaborate on documents, rather than leaving it to one or two designated authors. (BTW, I am _not_ proposing that we use Microsoft Word in the toolchain, nor that git isn't useful. I am not a fan of Word, and I am a fan of git. The point of mentioning Word is that change tracking is something it does right; the point of saying that git isn't good enough for this application is that it isn't, not to say that it isn't good enough for other applications.)
