Google's business model

You might be wondering - how come these two mathematicians are getting richer than Murdock, Buffett and what not... by just letting us browse the net for free.

Right. What they actually do, they sell words on an auction. For instance, Victoria Secret is paying $1 every time a sponsored link from Google refers to Victoria Secret site.

(The verb "refers" means the following: a link leads to Victoria Secret site, and the link is followed, and a header processed on Victoria Secret contains "referer" from Google.)

I actually love it. Stupid people pay, and greedy people pay, and the rest of the world enjoys.
