I'd be interested in hearing why you think numerous Fortune 500 companies that have existed long before Google and will exist long after Google is gone, feel the need to "game" the system and "break the rules"?
Surely, they are idiots, yes?
Perhaps, their products, in reality, suck and the masses of people who buy them are merely pawns?
Again, because you start of with the wrong assumptions, you come to faulty conclusions.
(Psst. As always I have to remind you it's about ROI.)
Everything else is really, truly, irrelevant.
Of course, I'm going on the assumption that one is running a business, not a successful hobby site
Here's another hint:
You still haven't explained to me why Keio University has a higher PR than Coca-Cola...
the most widely known word in the world.
