I spend a lot of time sending and receiving versions of articles via e-mail. These tend to be small, generally on the order of 2000 words. I like to think of myself as a good editor, being able to improve the wording and organization of things. Still, several authors want to make changes, which is fine -- many phrasings are a matter of taste and some pieces of technology and code change for the better before final press time.
Then there are authors who make larger changes. It's easy to say "Can you change this sentence here and this word there?" It's a lot more difficult when the author moves paragraphs around and reformats the text.
Oddly, this problem almost disappears on larger projects, such as books. (See The Making of BSD Hacks
Why isn't a similar solution viable for articles? They're too small! The overhead of setting up a repository with authentication is too big to be useful for a maximum of three or four revisions of a 2000-word article.
Does the overhead have to be that great? I don't think so. The overhead of setting up a mailing list that lasts a week for a dozen people and two dozen posts used to be too high to be worthwhile, but Mail::SimpleList shows one way to avoid that.
This subject bears more thought. There may be a general principle here.
