Yea-who,
The rank is based on number of posts. This is not a judgement of anyone's skill, knowledge or helpfulness only level of participation. It's built into the software, which is a generic "one size fits all" bulletin board package.
Rating a person's helpfulness is best left to the readers anyway. There are some people who might mean very well but have a drastically different approach to the sport. As an example, when casting questions come up, I often reccommend seeing a professional casting instructor whereas JF recommends going out fishing and practicising more. I imagine JF got to be the excellent fisherman he is following that advice, so I am not going to say you can't learn a lot on your own. I learned to cast by taking lessons and folks say I throw a nice line, so I'd say that you can save a lot of time and frustration my way too. But the two sets of advice are drastically different. For one reader, one of us is going to sound like a jerk. But really we are just trying to pass on what works for us.
Given that, who deserves a higher star rating? I'd hate to judge, unless I was the reader and trying to follow the advice. If the one approach made sense and worked, I'd listen to that guy the next time I had a question.
