I think sometimes people just outgrow a scenario that stays at the same level. As Treeco said, most of what is on the chainsaw forum is just drivel to someone of a professional level racing or chain builder. It is not very likely that that will be much of a forum item, because that strategy is rather jealously guarded. It seems to me that the result is they get bored and condescending and start to make a nuisance of themselves like a 17 year old in grade school. I think some of the climbers get burned out too after the seventh discussion of the pros and cons of the different climbing hitches. I think most people who have spent a lot of time here have learned a lot, but there does seem to come a time of diminishing returns and a feeling of watching reruns. I mean really, how do you regain your wide eyed innocence and enthusiasm when it has become ho hum!
