I think, if he actually did make the money he claims, he made it through his product sales and not blogging directly. Again, just an opinion, but I am a realist and realistically, I don't believe it has happened. Not without a team of bloggers, 1000 sites, and a whole lot of dedication....and even then, you have to pay your team of bloggers, pay your affiliates, and right on down the line.
Even if the boy made the million dollars tax would take 39% so he may live comfy but not a millionaire.
