The clear standard of excellence (as noted in the Pulitzer Prize winning "Greener Posters: CBlog's 100 Greatest") is to maintain a 10:1 Post to TP Ratio (TPR).
As an occasional poster, I have always been proud of sporting a solid TPR. FL is certainly the Bob Gibson (circa 1968) of TPR, while unnamed others wallow in a dearth of recognition.
I would also like to give credit to those mega-posters who are less likely to sport high TPR. Much like Antoine Walker heaving voluminously from beyond the arc with occasional success, these prolific pontificators are often of great value to the blog, but will always have a more challenging road to high TPR.
Some might say there is greater value to quality over quantity; other may argue quantity over quality. While both add value to this medium, it is a rare but treasured poster who provides both. TPs galore to those precious few.
