Right. You know, finally I did what one of us should have done some 8 or 9 messages back - I went and checked what you actually wrote:
> the popularity of her books suggests otherwise [my emphasis]
In other words, you weren't actually making the claim I thought you were - that popularity implies quality. So I'm sorry for missing your point originally.
I do disagree that popularity is evidence of quality; popularity is only evidence of broad appeal, and you'd still need to demonstrate a correlation between broad appeal and quality - I contend that no correlation exists. But that's a reasonable debate, not a logical fallacy.
But I have to ask - why didn't you tell me that I was refuting an argument you hadn't made...?
