Some interesting stuff, then realised it was from 2006, excellent just skip to the end to see how fantastically successful all the people at the start had been..... not so good reading at the end.
Can't understand why anybody with a genuinely good business idea would share it with somebody else, other than the fact they know that it has limited potential in the long run, do it long enough to generate a bit of profit and buzz, then sell it to the punters.
From what I can tell the central theme is marketing of other peoples products via the web, they have all the production costs and you just skim a little of the top via affiliation. Might have worked 3-4 years ago, the web is a totally different place these days.
