Can Google Stay on Top?

Anyone that watches "American Idol" knows -- the public is a fickle lot. Yesterday's potential Idol one day can be packing it in the next. The same could be said for Google. Right now, it's the market leader -- but so was Yahoo once. Now, according to a recent study, the difference between Google and other search engines is shrinking, with rivals only a couple of percentage points behind in search results.

I can hear the judges now...

Randy: "Yo Dawg, yo. It was a'ight. I wasn't feeling it though."

Paula: "Google, you have such amazing potential. We are all truly blessed to have you here with us."

Simon: "My advice would be if you want to pursue a career in the search-engine business, don't."
