i kind of suggested something like this some years ago

althoug not wiki, but more in a controlled form to avoid misinformation...

use a fixed template, to make the information uniform
and have a couple of editor's per subject, that review articles sent in... perhaps one or 2 to screen the articles and then send them on to the relevant editors per subject

problem with pure wiki is that anyone can crap up any existing article, or just produce new articles that make no sense, or duplicate articles...
