NoSuchURL.Com is intended to be a "home page" for your internet browser -- nothing more and nothing less.
It consists of a number of very popular websites that many people visit on an almost daily basis, along with some websites that contain useful and helpful information, and of course, a whole host of popular search engines!
As for who "us" is... well 'we' are not even really sure ourselves, so 'we' can't really answer that question... we're sure you understand :-D
