NO ONE CAN REPLACE GOOGLE Google runs over one million servers in data centers around the world,[14] and processes over one billion search requests[15] and twenty petabytes of user-generated data every day
Choosing the lesser of 2 evils is right.... Facebook will never "overthrow" Google... Could grab search market share, of course... Google has its hands in too many areas of our every day lives to be knocked off at this point.. Apps / Cloud Services / Mobile Devices / With Chromium it will be desktops, etc... / Phone Services and a hell of a lot more... Search isn't the only thing that Google is concerned with these days, so if they lose a bit of market share to FB... then Mark is doing what he wanted... Don't forget, Larry and Sergey plan to take over the world, and they have a lot more power, money and control than FB does... If FB went offline today and ALL of Google services went offline today, which one would cause more of an uprise?..... GOOGLE...
