Re: Breaking up might be good for Google
"advertising is where Google makes the big bucks."
erm ... no: advertisement is what makes Google money. Google is only an advertisement brokerage firm, that happens to use a particular tool for it. It's not Doubleclick that should be split-off from search, but Android, and may-be YouTube.
Let Google make money with search and maps and ads, but let Android free from Google. Actually, with Oracle-vs-Google over Java and Android, this might happen anyway, and rather sooner than later.
Same for Facebook with WhatsApp and Instagram.
