I have no idea how to register a domain BTW
"Authors" of such articles get paid, largely, based on copies sold. I.e. they have a direct vested interest in the propogation of their "information"
People that offer advice on the boards have no such vested interest. People here have spent countless hours reading and guinea-pigging themselves to determine the optimal methods for optimizing their potential. We share information and learn from each other. In hindsight, we can look back and see what, of all the various things we've tried, has been the most beneficial/efficient and we can then pass on that information to others so that they don't have to waste time (or potential for harm) experimenting on themselves in the same way. The only thing people here should expect from their offering of advice is that others do the same, so that we can all learn from each other.
When money is taken out of the equation, the truth has a tendency of being all the clearer.
