To all the people saying .xyz doesn't make sense, does it need to in order to convey that whatever.xyz is a
"website" that you access/navigate on a computer? No.
double-u double-u double-u dot whatever dot x y z MEANS "a website/virtual address", a virtual catalog or information resource accessed usually on a computer. That is all the meaning/association that is necessary.
The domain doesn't weigh as much as the content, if people like your site, they will remember your address.
Of course certain people will beg to differ, but still... function/value over appearances.
