"Isn't it a little unnerving, in a generic way, that a #1 search suggestion for any search term would be a site that explicitly imitates the look of a different site--"
You are right. I am sure lots of people type in their bank name in a google search bar when they want to log in to their bank.
"search suggestions" seem to be based on raw statistical likelihood.."
That's the thing. How likely is it that someone (besides the people reading this thread) has ever typed in "where is chuck norris"?
As for Dubai, am not sure why it would be trending now. I went to google, searched for Dubai, clicked on the news link at the top of the browser, and all the news was related to something else (Egypt, obamacare, trayvon martin, the lone ranger...)
Wait a minute... I looke some more... it is probably either because jamoriquai is going to be playing there, or because the Red Bull Breakdancing Competition is going to be there. Wow! Dubai is a pretty hip place after all...
