I agree with that statement. What I believe people want to know is the impact of various lists relative to other methods of sharing their thoughts with colleagues in related fields.
The simple answer is that nobody really knows how to measure impact in any absolute sense. Even relative impact is extremely difficult to measure. And any numbers that are generated are suspect.
