you make a lot of sense... I agree frequency is not at all tied to quality... I've come across all types... those who are prolific and are great at conveying what you need... those that like to write of their exploits but add nothing in terms of giving the rest of us a glimpse into what the gal is really like... then there are the ones who only write now and then... either because they only see a gal now and then, or only write when they feel it adds something... and again... these are both good and bad in terms of the content.  

As for the OP... the key to credibility is not the number... but the content... including grammar, spelling and paragraph breaks... It is hard to take someone serious when they write poorly.
