The unfortunate thing about Wikipedia is that there are two kinds of people who make substantive edits to it.
On the one hand, you have people who create stuff. They are usually casual editors, who very often don't even bother to create an account, or even if they do, they only ever make a dozen or two edits. They tend to know next to nothing about Wikipedia policies and guidelines, but they often have some degree of expertise in the subject matter itself. (Incidentally, the article "Who Writes Wikipedia?" by Aaron Swartz contains some interesting research that shows that this is a surprisingly accurate picture.) And they live in the Real World.
On the other hand, you have pepole who delete stuff. They tend to be established Wikipedians with thousands or even tens of thousands of edits and an encyclopedic knowledge of Wiki policies and guidelines, but on the whole they know nothing whatsoever about the subject matter that they're deleting. They live in some kind of Matrix-esque alternate reality entirely defined by WP:RS -- which, in practice, means that if you can't find it in a national newspaper or a scholarly journal, it doesn't exist and must therefore be a dangerous heresy to be ruthlessly suppressed. They tend to treat Wikipedia as an MMORPG which they play to win, and they usually do, unless they're up against another Wikipedia-is-an-MMORPG type who is better at it than they are. And they are giving Wikipedia a bad name, as well as alienating a lot of would-be Wikipedians.
The fact of the matter is that there's plenty that we could say about Colemak that's easily and almost trivially verifiable in Real Life with just a spot of Googling and common sense, but because it is invisible within the WP:RS Matrix, according to the auditors of reality it doesn't exist.
