I agree with you. You can game the system buy buying links in a clever manner. I havent found authority people who will link to you for free. I have studied websites that have been running the show for years. Except for amazon, facebook and the like that have made a name that google wouldnt dare to downgrade, some other big people buy links and do alot of nothing else. They have been ruling their niche for years. Again. What content do paypal, facebook, twitter, amazon have. they all look like charlatans. The only site that gets what it deserves in terms of content is wikipedia; no one beats that.
