No, I am not asking you a question, but a Bing feature definitely wants to ask you this. Incidentally, the URL http://when.you.have.google.why.use.bing.com/ displays a Bing search page. Weird right? Not exactly, as the main domain is still Bing.com :-)
By the way, you can also search at http://techie-buzz.bing.com/ too. Ok, enough messing around. Bing has a hidden feature which allows you to append any sub domain to Bing.com and then search their decision engine.
To create your own URL, just change yourcustombingword in the URL http://yourcustombingword.bing.com to anything you want. Have fun and impress your friends that you have a personal Bing search page.
