1. Appeals to authority aren't actually bad if the authority is actually an authority. If an authority on this subject exists at all, it would appear that it would be Goodman.
2. Much of Goodman's evidence is soft evidence- reviews of gaming stores, feedback over time from distributers and retailers, and so on. He can't present his evidence in any sense other than a vaguely journalistic one- he could quote mine his memory of some interview with a random gaming store, but that's about it. And the value of that would pale in comparison to the value of his opinion, which presumably includes within it all of the individual bits of feedback he's gotten over time from multiple sources, instead of just one or two quotes. This is not atypical for this type of information.
3. If you're going to call Mr. Goodman a liar, just get on with it instead of dropping insinuations.
Goodman actually has good data, its just "soft" like I discussed in my earlier post. Even his "soft" evidence is more meaningful than anyone elses opinion that doesn't take that data into account, because since there isn't any better data to be obtained, any other opinion put forth even without the "soft" data Goodman uses is purely opinion. At least what Joe writes about is based upon what data is known. Such as WOTC's soft sales figures given in court documents ("Hundreds of thousands of core sets sold") to feedback he has collected from over a hundred stores, plus his years of SUCCESSFULLY running a business. So his "opinion" is based upon far harder facts and experience in the field than anyone elses opinion would be.
In fact, I would count Joe's opinion above pretty much anyone elses in the business.
For instance, Clark hasn't been visiting and communicating with so many stores, he hasn't stated whether or not he has read court documents to get even "soft" sales numbers of TSR or WOTC, etc...
I would rate Goodmans opinion over Scott Rouses and Erik Mona, etc... since I doubt they have personally invested the time and effort into collecting this data and information like Joe has. Their opinion is all from second hand and distant analysis and opinions. Joe's is from the streets themselves, first person, as well as from his own personal research and reading of court documents, which are "public", when you know how to look, which is why the soft data for WOTC's 4E sales are even known.
So I am sure people will argue with Joe's opinion, and try to devalue what he says, but I doubt they will be able to sway me unless they have better information from better sources than Joe has.
So as far as I am concerned, Joe is right. He is the ONE person who does know best. So until someone comes along offering better research sources, Joe is the Guru.
