I just came here from seeing this message in the bottom of all sites list:
Want to start your own Stack Exchange Q&A site? Check out Area 51. Our friendly robots are waiting.
Does this mean if I have my own project, I can start my own SE Q&A site exclusively about it? An example could be Minecraft.SE. I could only guess that if Notch came down here and asked, the site might get created, but what about less popular (less than triple-A game or Wordpress-popular) projects?
