I too read this board regularly and post very infrequently. The reason being that with the combination of living in a big city away where any decent fishing is a trip and my job/life I don't have time to fish regularly so i am a perennial "newbie".
Many of the regular posters are people who either have gotten to know each other over the years and who have a lot of experience/expertise to share. The nature of the beast is there will be a lot more people who are gaining from the board than those who actively/regularly post.
