Unlike yourself, I didn't claim to know of any relationship between any particular claims and the real number of bitcoin users. I honestly don't know if there are more or less than 1 Million users. I mentioned it to highlight your lack of evidence. Referencing the logic and "data" of others, who don't have any evidience of their own, doesn't constitute evidence either. You do this a lot, make grand arguments that you cannot support. I'm surprised you're not either a lawyer, a politician or a preacher.
The thread which I started in October, includes most of the data and reasoning behind the 2.0 million number. As perhaps the person who has put the most energy and talent to finding this out (over the last 4 months anyway), I am open to answer your questions for example if you want to define "user" in a different way, how it would affect the total.
Definition used there is "Person who directly or knowingly beneficially owns at least
BTC0.001 at the time of census."
If Mt.Gox never pays out, there will be a dent in # of owners...
