Need thousands of new major articles

Yup. In almost every area, we need dozens of articles that anyone who knows the field can name off the top of their head. For those who can't, there are redlinks. (Although I started out thinking a redlink meant it had been deleted and shouldn't be re-created!) We also have an appalling number of one-line stubs. The problem is all the worse outside en.wikipedia, because it's so much larger. It's simply not true that we're near the useful limit of articles, or even that the missing articles are hard to find info on.
