senior editors and baseline quality
Two people may know more than one if it comes down to a simple addition, but some of the things they know will contradict each other; the things they agree on knowing will be a lot less than what one person knows. As to the useful work they produce, there are many cases where two (or ten) people together do not produce half (or a tenth) the amount of work one person can do (if he knows what he is doing). It all depends. - Brya 05:43, 23 January 2010 (UTC)
Indeed, the idea is not to keep such a project as an elite club, but more as a driving force. A simple example: today as an admin I had to make a decision on an article about a computer game. I have myself no idea about the computer games. The deletion review was not active, only the author of the article voted (obviously, against deletion). What I did I went to the computer games project, asked their opinion, and eventually deleted the article. That was my responsibility, but eventually their expertise.
