On deletion, blocking newbies, aggressive user-talk templates, and slowing growth
Wikipedia growth has slowed dramatically - both in the # of new users signing up and in the # of new articles being created. Some say that we're approaching having "an article about everything"... this sounds to me like physicists at the end of the 19th century saying we'd just about resolved all of physics. The world is full of tens of millions of creative works, billions of people, and trillions of places, things, and concepts. We're not there yet.
However, we've developed a whole network of policies and guidelines to help the project grow smoothly, without unusual growth in certain subgenres. I believe Wikipedia needs to continue its steady pace of growth, and to expand to cover the hundreds of enormous areas currently untouched; this page is for gathering the arguments to the contrary, and to see why as a community we are backing away from some of our founding tendencies.
