And,
unfortunately, that's how articles on every sub-subject get created,
because people often don't want to slog through editing down an overly
large article. It's easier to go off and create a little article on
your own, that way you get all the pride of ownership and creation and
none of the hassle of editing conflicts.
That's a bit of an assumption of bad
faith there and doesn't match my
own experiences. When I create sub-articles it's usually by splitting
pieces off of an existing article, I don't often write the material from
scratch.
Bad faith? How so? I'm just positing an explanation for how these
things happen.
