a funny metaphor

if, internet is the ground

then, google is the only road of the internet world,and websites are houses! website navigators are the map
and,what else do we need in our cyber-world? we need a new sophiscated road, a new car(browser is the old road),a new sophiscated website navigator, a street lamp,…… obviously ,the road is a public good ,in real life world or in cyber world.

much more interesting, the google thing breaks up the classic economic theory, that's,the public good can't be allocated by the market ,cause the google sounds good,although some shortcomings.but more important thing is ,the earnings of public good is captured by google mostly,and that's a definite monopoly ,and monopoly is not good for market,as classic eco theory points out ,but the google works well ,i have no idea why ,maybe that's the specialication of the internet!
