I just realized that Ask Ubuntu is actually a proposed site on Area 51, and I was curious why it got its own URL to be distinguished from others.
Here on Arqade, if I type
https://arqade.com/, it redirects me to
https://gaming.stackexchange.com/. Same thing goes for Ask Different.
Why did Ask Ubuntu get its own URL while Arqade can't? Is there a possibility that we will get Arqade (or Ask Different) its own URL?
