On the homepage, we claim to seek to write 100,000 articles. We have nearly 30,000. As '24' pointed out the other day, with 30,000 articles we don't have one on the Amazon Rain Forest. I also just noticed that we don't have one on Real Estate Investment Trusts. And we don't have one on 'Corgi', which is a breed of dog, nor do we have articles on many other dog breeds.
The way we arrived at that 100,000 number was extremely unscientific. Britannica claims to have 66,000 articles. And we wanted to have more. :-)
I would never have thought that someone would interpret the 100,000 figure as the _maximum_, as part of a critique of us that we are nearly 1/3 of the way "done" and yet don't cover X, Y, and Z.
I wonder how many articles we really should expect to have. Obviously, we'll never be "done". But the largest dictionaries of English list around 500,000 words.
