I haven't quoted Nick Carr in way too long

So here is something from a recent blog entry:
The quality of any entry in Wikipedia, for instance, is ultimately determined not by how many people work on it but by how many talented people work on it. An entry written by a single expert will be better than an entry written by a hundred fools. When you look deeply into Wikipedia, beyond the shiny surface of "community," you see that the encyclopedia is actually as much, or more, a product of conflict than of collaboration: It's an endless struggle by a few talented contributors to clean up the mess left by the numbskull horde.
