KP, what I meant was that Aaron has a keyword research TOOL. and that I wouldn't want to carry out KW research uning that as it is effectively feeding the site owner a nice set of niches to go after.
So what I was satying is that an unscrupulous marketer could provide the KW research tool for free, and use it to have others provide him/her with a string of niches to exploit. That was what I meant by ending up competing against someone like Aaron, you would research a niche, HE also gets the data researched, and can cherry pick the easiest pjhrases etc.
Hope I have made it more clear now.
